Description

Technical Field

[0001] This application relates to the field of optical fiber cooling technology, and in particular to a cooling structure for an optical fiber stripper and a laser having the same. Background Technology

[0002] CPS (Cladding Power Stripper), also known as a fiber mode stripper, is one of the important components in fiber lasers. Its function is to strip the pump light and higher-order modes transmitted through the cladding to ensure the beam quality of fiber transmission.

[0003] Existing technologies typically employ conductive cooling to address the thermal effects of fiber lasers, especially high-power fiber lasers. In this conductive cooling method, the fiber stripper is fixed within a sealed metal cavity, and heat accumulated within the fiber stripper is dissipated by a coolant placed between the fiber stripper and the sealed metal cavity. This structure suffers from several drawbacks: the coolant is in direct contact with the fiber stripper surface, allowing impurities in the coolant to adhere to the fiber stripper surface and reduce heat dissipation efficiency; and the sealed metal cavity has a complex structure and poor encapsulation reliability, making it prone to leakage. Summary of the Invention

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art. This application provides a cooling structure for an optical fiber stripper and a laser having the same, so as to solve the technical problems of poor sealing of the cooling structure of the optical fiber stripper and the influence of impurities in the coolant on the heat dissipation effect of the optical fiber stripper body in the prior art.

[0005] This application provides:

[0006] A cooling structure for an optical fiber stripper includes:

[0007] Fiber optic stripper body;

[0008] A cooling assembly has a cavity communicating with the outside world. The cavity has two ports spaced apart. The fiber stripper body enters the cavity from one of the ports and exits the cavity from the other port.

[0009] A fixing component is connected to the fiber stripper body and the cooling component respectively, so that at least one of the ports is connected to the outside.

[0010] In addition, the cooling structure of the fiber optic stripper according to this application may also have the following additional technical features:

[0011] In some embodiments of this application, the cooling assembly has a first sidewall that encloses the cavity, and the fixing assembly includes a support and an adjusting member. The support is connected to the fiber stripper body, and the adjusting member is connected to the support. The adjusting member drives the support to move to change the distance between the fiber stripper body and the first sidewall.

[0012] In some embodiments of this application, the support member is spaced apart from the cooling assembly, and the support member is disposed at both ends of the fiber stripper body.

[0013] In some embodiments of this application, the support member is connected to the cooling assembly, the support member is disposed within the cavity, or the support member is disposed at the port.

[0014] In some embodiments of this application, when the support member is disposed in the cavity, the cooling assembly further has a first connecting portion, the first connecting portion having a hollow structure, the first connecting portion communicating with the cavity, and the adjusting member passing through the first connecting portion and slidably connected to the inner wall of the first connecting portion.

[0015] In some embodiments of this application, the adjusting member is snapped or threaded onto the inner wall of the first connecting portion.

[0016] In some embodiments of this application, when the support member is disposed at the port, the support member has a first through hole, the adjustment member is embedded in the first through hole, and the fiber stripper body passes through the adjustment member.

[0017] In some embodiments of this application, the adjusting member has a plurality of second through holes, the second through holes are connected to the cavity, the plurality of second through holes are arranged in an array, and at least partially overlap between two adjacent second through holes.

[0018] In some embodiments of this application, the cooling structure of the fiber optic stripper further includes a liquid cooling device, the cooling assembly contains a coolant, and the liquid cooling device is connected to the cooling assembly so that the coolant circulates between the liquid cooling device and the cooling assembly.

[0019] This application also provides a laser, including the aforementioned fiber stripper cooling structure.

[0020] Compared with the prior art, the beneficial effects of this application are as follows: This application proposes a cooling structure for an optical fiber stripper. By setting the optical fiber stripper body to pass through the cavity, direct contact between the optical fiber stripper body and the coolant is prevented, avoiding impurities adhering to the surface of the optical fiber stripper body, which could lead to insufficient heat dissipation and damage to the device. Furthermore, this application also provides a fixing component to fix the optical fiber stripper body and the cooling component, preventing relative movement between them and avoiding a reduction in cooling effect due to the optical fiber stripper body detaching from the cavity. At least one port is also provided to connect to the outside, so that part of the heat generated by the optical fiber stripper body is directly conducted to the outside air, and the other part of the heat is transferred by the cooling component. These two heat transfer methods work simultaneously to improve the cooling efficiency of the optical fiber stripper body and improve the cooling effect.

[0021] In addition, by incorporating the aforementioned fiber stripper cooling structure into the laser, the output power of the laser is increased due to the improved cooling efficiency of the fiber stripper body. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0036] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0039] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] like Figure 1 As shown, this application provides a fiber optic stripper cooling structure 100 for cooling the fiber optic stripper. The fiber optic stripper cooling structure 100 includes a fiber optic stripper body 110, a cooling assembly 120, and a fixing assembly 130.

[0041] The cooling assembly 120 has a cavity 124 communicating with the outside. The cavity 124 has two spaced-apart ports 1241. The fiber optic stripper body 110 enters the cavity 124 through one port 1241 and exits the cavity 124 through the other port 1241. A fixing assembly 130 is connected to both the fiber optic stripper body 110 and the cooling assembly 120. This structure prevents the fiber optic stripper body 110 from directly contacting the coolant, thus avoiding the problem in related technologies where impurities in the coolant adhere to the surface of the fiber optic stripper body 110, reducing the cooling effect. Furthermore, by using the fixing assembly 130 to fix the fiber optic stripper body 110 and the cooling assembly 120, relative movement between them is prevented, avoiding a reduction in cooling effect due to the fiber optic stripper body 110 detaching from the cavity 124.

[0042] The inventors discovered that in related technologies, the fiber optic stripper body 110 is fixed inside the cavity 124, but the two ports 1241 of the cooling assembly 120 are sealed. At the same time, the fiber optic stripper body 110 is kept separate from the first sidewall 121 of the cavity 124. This structure means that the fiber optic stripper body 110 can only dissipate heat in one way, that is, the heat generated by the fiber optic stripper body 110 can only be transferred to the cooling assembly 120 through the air inside the cavity 124, and then the cooling assembly 120 transfers the heat. This cooling method has low heat dissipation efficiency and cannot be used for the heat dissipation of high-power fiber optic strippers.

[0043] In response to the above problems, such as Figures 2 to 4 As shown, this application also provides at least one port 1241 that connects to the outside. In this way, part of the heat generated by the fiber optic stripper body 110 is conducted to the outside air through the cavity 124, and the other part of the heat is transferred by the cooling component 120. These two heat transfer methods work simultaneously to improve the cooling efficiency of the fiber optic stripper body 110 and improve the cooling effect.

[0044] The cooling assembly 120 includes a first sidewall 121 forming a cavity 124.

[0045] It should be noted that in this application, there are three possible positional relationships between the fiber optic stripper body 110 and the first sidewall 121: the fiber optic stripper body 110 abuts against the first sidewall 121; the fiber optic stripper body 110 and the first sidewall 121 are spaced apart; and a portion of the fiber optic stripper body 110 abuts against the first sidewall 121, while the remaining portion is spaced apart. These three methods can be selected according to actual needs.

[0046] As an example, such as Figure 2As shown, when the fiber optic stripper body 110 abuts against the first sidewall 121, the first sidewall 121 is made of a metal material, such as iron, aluminum, or copper. In this way, the heat generated by the fiber optic stripper body 110 can be quickly conducted to the first sidewall 121 and transferred by the cooling assembly 120, or it can be transferred from the cavity 124 to the outside. The two heat dissipation methods work simultaneously, improving cooling efficiency.

[0047] As an example, such as Figure 3 As shown, when the fiber optic stripper body 110 is spaced apart from the first sidewall 121, this positional relationship makes the heat dissipation of each part of the fiber optic stripper body 110 more uniform. Of course, the first sidewall 121 is preferably made of a metal material, such as iron, aluminum, or copper. In this way, the heat generated by the fiber optic stripper body 110 can be transferred from the cavity 124 to the outside, and can also be quickly conducted from the cavity 124 to the first sidewall 121, where it is then carried away by the cooling assembly 120, improving cooling efficiency.

[0048] As an example, such as Figure 4 As shown, when part of the fiber stripper body 110 abuts against the first sidewall 121, and the remaining part of the fiber stripper body 110 is spaced apart from the first sidewall 121, it is preferable that the fiber stripper body 110 near the two ports 1241 is spaced apart from the first sidewall 121, and the remaining part of the fiber stripper body 110 abuts against the first sidewall 121.

[0049] It is understandable that the airflow speed is slow in the middle part of the cavity 124, so the fiber stripper body 110 is placed in the middle part of the cavity 124 to abut against the first sidewall 121 to accelerate heat dissipation. At the same time, the port 1241 of the cavity 124 is connected to the outside, and the airflow speed is fast, so the fiber stripper body 110 is spaced apart from the first sidewall 121 at the port 1241 to improve heat dissipation efficiency.

[0050] Furthermore, the cavity 124 can be configured to transition or interference fit with the fiber stripper body 110. In this way, the fixing component 130 can be omitted, and the function of fixing the fiber stripper body 110 can be achieved, simplifying the fiber stripper cooling structure 100.

[0051] Based on the three positional relationships between the fiber stripper body 110 and the first sidewall 121, it can be understood that the cavity 124 can be cylindrical, dumbbell-shaped, etc., and the shape of the cavity 124 can be set according to actual needs, which will not be specifically limited here.

[0052] The fixing component 130 includes a support member 131 and an adjusting member 132. The support member 131 is connected to the fiber optic stripper body 110, and the adjusting member 132 is connected to the support member 131. The adjusting member 132 drives the support member 131 to move to change the distance between the fiber optic stripper body 110 and the first sidewall 121, thereby changing the positional relationship between the fiber optic stripper body 110 and the first sidewall 121 among the three positional relationships described above, thereby improving the practicality of the fiber optic stripper cooling structure 100 of this application.

[0053] The fixing component 130 is connected to the fiber optic stripper body 110 and the cooling component 120.

[0054] Specifically, the support member 131 is spaced apart from the cooling component 120, and the support member 131 is located at both ends of the fiber optic stripper body 110; or, the support member 131 is also connected to the cooling component 120.

[0055] When the support member 131 is also connected to the cooling assembly 120, the support member 131 is disposed in the cavity 124 or at the port 1241.

[0056] The fiber optic mode stripper cooling structure 100 of this application also includes a liquid cooling device 200.

[0057] When the support member 131 and the cooling assembly 120 are spaced apart, the cooling assembly 120 is mounted on the liquid cooling device 200, and the support member 131 is mounted on the liquid cooling device 200.

[0058] As an example, the support member 131 is any one of the following shapes: annular, arc-shaped, or zigzag-shaped. The two ends of the fiber optic stripper body 110 are respectively mounted on the two support members 131. The adjustment member 132 adopts a telescopic sleeve structure, one end of which is fixed to the liquid cooling device 200, and its telescopic end is connected to the support member 131, thereby driving the two ends of the fiber optic stripper body 110 to move and change the positional relationship between the fiber optic stripper body 110 and the first sidewall 121.

[0059] When the support member 131 is disposed within the cavity 124, such as Figure 5 As shown, the cooling assembly 120 also has a first connecting portion 126, which communicates with the cavity 124. An adjusting member 132 passes through the first connecting portion 126 and is slidably connected to the inner wall of the first connecting portion 126. Specifically, the adjusting member 132 is engaged or threadedly connected to the inner wall of the first connecting portion 126.

[0060] It should be noted that the first connecting part 126 is a hollow cylinder, and the first connecting part 126 is sealed to the cooling assembly 120 or integrally formed to prevent coolant leakage.

[0061] As an example, the adjusting member 132 is a screw, the supporting member 131 is a rubber block disposed at the end of the screw, the screw passes through the first connecting part 126, and the hole wall of the first connecting part 126 is threadedly engaged with the screw.

[0062] There are two first connecting parts 126, which are distributed on both sides of the fiber stripper body 110 in the radial direction. There are also two screws, with one screw corresponding to each first connecting part 126. In this way, the fiber stripper body 110 is clamped between the two screws. By rotating the two screws, the two ends of the fiber stripper body 110 are moved, changing the positional relationship between the fiber stripper body 110 and the first sidewall 121.

[0063] Of course, the number of first connecting parts 126 can be set to more. Multiple first connecting parts 126 can be arranged along the axial direction of the fiber stripper body 110 or multiple first connecting parts 126 can be arranged along the circumference of the fiber stripper body 110. The arrangement principle is as described above, and will not be repeated here.

[0064] When the support member 131 is located at port 1241, such as Figure 6 As shown, the support member 131 has a first through hole 1311, the adjustment member 132 is embedded in the first through hole 1311, and the fiber stripper body 110 passes through the adjustment member 132.

[0065] The adjusting member 132 has multiple second through holes 1321, which communicate with the cavity 124. The multiple second through holes 1321 are arranged in an array, with at least partial overlap between adjacent second through holes 1321. This allows the adjusting member 132 to move among the multiple second through holes 1321, changing the positional relationship between the fiber optic stripper body 110 and the first sidewall 121. Furthermore, the cavity 124 communicates with the second through holes 1321, and the second through holes 1321 communicate with the outside environment, improving the heat dissipation efficiency of the fiber optic stripper body 110.

[0066] It should be noted that the manufacturing process of the fiber optic stripper body 110 is as follows:

[0067] S10: Cut a double-clad (or multi-clad) optical fiber of a specified length, remove the coating layer of the corresponding length as required to form a bare fiber, and make a stripped fiber 111 by chemical etching of the inner cladding surface of the bare fiber.

[0068] S20: Clean the bare fiber area on the stripped fiber 111 with an organic solvent using ultrasonic cleaning.

[0069] S30: Put the cleaned stripped fiber 111 onto the glass tube 112, and fix the glass tube 112 on the bare fiber area.

[0070] S40: Assemble the fixed stripped fiber 111 with the glass tube 112;

[0071] S50, the fiber optic stripper 110 has been fabricated.

[0072] like Figure 6 and Figure 8 As shown, it can be understood that when the fiber optic stripper body 110 moves on the adjusting member 132, the glass tube 112 or the stripped fiber 111 will rub against and be squeezed against the wall of the second through hole 1321, causing damage to the glass tube 112. Therefore, the adjusting member 132 is made of a flexible material, such as rubber or plastic, to prevent the structure of the fiber optic stripper body 110 from being damaged during movement.

[0073] Furthermore, multiple third through holes 1312 can be opened on the support 131. The third through holes 1312 connect the cavity 124 and the outside world, thereby improving the heat dissipation efficiency of the fiber optic stripper body 110.

[0074] The inventors also discovered that the liquid cooling device 200 and the cooling component 120 in the related technology are set separately. The coolant in the cooling device needs to circulate between the liquid cooling device 200 and the cooling component 120 through pipelines. The connection structure of the pipelines is complicated, which is not conducive to the miniaturization of the fiber optic stripper cooling structure 100.

[0075] In this application, the liquid cooling device 200 is a water-cooled plate integrated into the laser.

[0076] like Figure 1 and Figure 7 As shown, the cooling assembly 120 contains coolant, and the liquid cooling device 200 is connected to the cooling assembly 120 so that the coolant circulates between the liquid cooling device 200 and the cooling assembly 120.

[0077] The cooling component 120 is roughly rectangular in shape.

[0078] Specifically, the cooling assembly 120 includes a first sidewall 121 forming a cavity 124, a second sidewall 122 spaced apart from the first sidewall 121, and two bottom walls 123 connecting the first sidewall 121 and the second sidewall 122. The first sidewall 121, the second sidewall 122, and the two bottom walls 123 are connected to form a structure with a sealed cavity 127. This sealing structure is simple and less prone to leakage problems due to poor sealing.

[0079] Furthermore, the second sidewall 122 has at least two second connecting portions 125, which are hollow and communicate with the sealing cavity 127. The liquid cooling device 200 has a corresponding connecting hole 212. The second connecting portion 125 is inserted into the connecting hole 212. In this way, the coolant flows into the sealing cavity 127 from one second connecting portion 125 and flows out of the sealing cavity 127 from the other second connecting portion 125 into the water cooling plate. This allows the coolant to flow in the pipes in the sealing cavity 127 and the water cooling plate. The circulating flow function of the water cooling plate drives the flow of the coolant in the sealing cavity 127, thereby transferring the heat generated by the fiber optic stripper body 110 to the water cooling plate and improving the heat dissipation efficiency.

[0080] The second sidewall 122 is fixed to the water-cooling plate. The second sidewall 122 is preferably made of metal. In this way, the heat of the coolant is quickly conducted from the second sidewall 122 to the surface of the water-cooling plate, thereby accelerating the heat dissipation of the coolant.

[0081] like Figure 7 , Figure 9 and Figure 10 As shown, the liquid cooling device 200 includes a connecting plate 210, a cooling channel 220, a cold source (not shown) and a pressure pump (not shown). A connecting hole 212 is opened in the connecting plate 210, the cooling component 120 is fixed on the connecting plate 210, and the second connecting part 125 is inserted into the connecting hole 212.

[0082] The connecting hole 212 is connected to the cooling channel 220, thereby connecting the sealing cavity 127 and the cooling channel 220. The cold source is connected to the cooling channel 220 to transfer the heat of the coolant in the cooling channel 220. The pump drives the coolant to circulate between the cooling assembly 120 and the liquid cooling device 200, so that the cold source can cool the coolant passing through the cooling assembly 120, thereby achieving a cooling effect on the fiber optic stripper body 110.

[0083] It is understandable that when the coolant circulates between the cooling assembly 120 and the liquid cooling device 200, there is a possibility of leakage at the connection between the connecting hole 212 and the second connecting portion 125. Additionally, it may cause the cooling assembly 120 to move on the connecting plate 210. Preferably, a sealing ring 129 is fitted over the outside of the second connecting portion 125. This sealing cavity 127 is used to seal the connection between the connecting hole 212 and the second connecting portion 125 to prevent leakage.

[0084] Preferably, the cooling assembly 120 further includes a plurality of connecting posts 128, and the connecting plate 210 is provided with at least two connecting holes 211. The connecting posts 128 are threaded or snapped into the connecting holes 211, thereby fixing the cooling assembly 120 onto the connecting plate 210.

[0085] It should be noted that the connecting post 128 is provided through the sealing cavity 127. Specifically, the connecting post 128 only passes through the second side wall 122, and a sealing structure, such as a rubber sealing ring, is provided at the connection between the second side wall 122 and the connecting post 128 to ensure the sealing performance of the sealing cavity 127.

[0086] In this embodiment, the connecting posts 128 are disposed near the second connecting portions 125, and two connecting posts 128 are disposed around the periphery of each second connecting portion 125. Correspondingly, two connecting holes 211 are disposed around the periphery of each connecting hole 212. This structure allows the connecting posts 128 to be assembled with the connecting holes 211, thus providing positioning and guidance for the assembly of the second connecting portions 125 and the connecting holes 212.

[0087] like Figure 9 and Figure 11 As shown, it should be noted that the fiber optic mode stripper cooling structure 100 provided in this application is suitable for cooling the fiber optic mode stripper body 110 of low power, medium power, high power and ultra-high power.

[0088] For example, when the fiber optic stripper cooling structure 100 of this application cools a low-power or medium-power fiber optic stripper, coolant does not need to be introduced into the sealed cavity 127; natural cooling is achieved through the structure connecting the port 1241 of this application to the outside. Alternatively, without coolant being introduced into the sealed cavity 127, the cooling assembly 120 is fixed to the connecting plate 210 of the liquid cooling device 200, and cooling is achieved simultaneously through natural cooling and the cooling effect of the liquid cooling device 200.

[0089] For example, when the fiber optic demodecler cooling structure 100 of this application cools the high-power or ultra-high-power fiber optic demodecler body 110, coolant is introduced into the sealed cavity 127 and the coolant circulates in the sealed cavity 127 and the cooling channel 220 of the liquid cooling device 200. This allows the heat generated by the fiber optic demodecler body 110 to be quickly conducted to the connecting plate 210 and transferred by the cooling component 120, or it can be transferred from the cavity 124 to the outside. The two heat dissipation methods work simultaneously to improve cooling efficiency.

[0090] Understandable, such as Figure 11 As shown, in order to enable the fiber optic stripper cooling structure 100 of this application to be quickly adapted to cool fiber optic stripper bodies 110 of various power, the second connecting part 125 can also be disposed on the side of the cooling assembly 120.

[0091] Specifically, the cooling assembly 120 is generally rectangular in shape, with its bottom surface abutting against the connecting plate 210 of the liquid cooling device 200. Ports 1241 are provided on two of its sides, and second connecting portions 125 can be provided on the other two sides. Furthermore, the two second connecting portions 125 can be provided on the same side or on two spaced-apart sides.

[0092] Furthermore, the second connecting portion 125 is connected to the liquid cooling device 200, thereby allowing the coolant to circulate within the sealed cavity 127 and the cooling channel 220. A flexible hose 230 can be provided to connect the second connecting portion 125 and the cooling channel 220. An adhesive layer 240 is provided on the bottom surface of the cooling assembly 120 to bond the bottom surface of the cooling assembly 120 to the connecting plate 210. As an example, the adhesive layer 240 can be thermally conductive silicone grease, which not only has adhesive properties but also good thermal conductivity, allowing the heat generated by the fiber optic stripper body 110 to be quickly transferred to the connecting plate 210, thereby improving cooling efficiency.

[0093] When cooling the medium- and low-power fiber optic stripper, the aforementioned flexible tube 230 can be removed, and the second connection 125 can be sealed to ensure good sealing of the sealing cavity 127. This allows for natural cooling through the structure connecting the port 1241 to the outside. Alternatively, without coolant flowing into the sealing cavity 127, the cooling assembly 120 can be fixed to the connecting plate 210 using the adhesive layer 240, utilizing both natural cooling and the cooling effect of the liquid cooling device 200 for simultaneous cooling.

[0094] When cooling the high-power and ultra-high-power fiber optic stripper body 110, the aforementioned flexible hose 230 is connected between the second connection part 125 and the cooling channel 220, allowing the coolant to circulate within the sealed cavity 127 and the cooling channel 220. This allows the heat generated by the fiber optic stripper body 110 to be quickly conducted to the connection plate 210, where the cooling assembly 120 transfers the heat, or it can be transferred from the cavity 124 to the outside. The simultaneous action of these two heat dissipation methods improves cooling efficiency.

[0095] In addition, when the second connection part 125 is located on the side, the location of the leak can be quickly located, making maintenance convenient.

[0096] This application also provides a laser, including the fiber stripper cooling structure 100 in any of the above embodiments. Since the fiber stripper cooling structure 100 improves the cooling efficiency of the fiber stripper body 110, the output power of the laser is increased.
