[0001] The present disclosure relates to the field of laser technology, and in particular to an optical fiber processing method based on an optical fiber laser and a laser. Background Art

[0002] The core component of fiber laser is doped fiber. During the wavelength conversion process of doped fiber, a lot of heat is generated. How to properly dissipate the heat of doped fiber has become an important process problem affecting the reliability of fiber laser.

[0003] In the early days, the heat dissipation problem was solved by thermal grease or by the contact between the optical fiber and the heat sink. However, thermal grease has the problem of silicone oil precipitation. After a period of use, its heat dissipation capacity will decrease due to the precipitation of silicone oil. The heat dissipation method that only relies on contact with the heat sink has a general heat dissipation effect and is only suitable for low-power fiber lasers. Summary of the invention

[0004] Therefore, in order to solve the above-mentioned heat dissipation problem of the existing fiber laser, the present disclosure provides a new fiber processing method based on fiber laser and a laser to overcome the heat dissipation problem of the laser.

[0012] Optionally, when winding the optical fiber, the following processing steps are also included: jig assembly, assembling the second jig with the first jig;

[0013] When the optical fiber is coiled, the optical fiber is placed along the optical fiber installation groove of the second jig so as to be coiled on the optical fiber installation grooves of the first jig and the second jig.

[0014] Optionally, the following processing method is also included when winding the optical fiber: placing the fusion point on the fusion point protection structure on the first fixture, and then winding the non-fusion-spliced ​​optical fiber part along the optical fiber installation groove to place the optical fiber on the first fixture and the second fixture.

[0015] Optionally, when the optical fiber is coiled, the first device and the front end portion of the optical fiber are placed in the guide channel of the first fixture, and the coiled portion of the optical fiber is placed on the first surface of the first fixture, so that when the optical fiber is transferred, the front end portion of the optical fiber, the coiled portion of the optical fiber and the first component of the laser are placed in sequence;

[0016] Wherein, the guide channel is recessed downward from the first surface of the first jig.

[0017] Optionally, after removing the first fixture, the fusion point protection structure and the coiled portion of the optical fiber are fixed to the first component by solidifying the liquid glue.

Then, after removing the first fixture, the coiled portion of the optical fiber is fixed to the first component by liquid glue (optical fiber re-fixation). The above method no longer uses tape, avoids residual air in the tape, and thus improves the heat dissipation effect of the laser. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] It should be understood that the exemplary embodiments described herein should be considered only for descriptive purposes and not for limiting purposes. Descriptions of features or aspects in each exemplary embodiment should generally be considered applicable to similar features or aspects in other exemplary embodiments.

[0036] The applicant has learned that there is a method of installing optical fibers by first machining a groove on the heat dissipation base plate of the laser, then placing the optical fiber in the groove, and finally potting it with a heat-conducting potting material. Since the optical fibers are separated by the grooves, the heat interaction between the optical fibers can be effectively avoided. However, the optical fiber cannot be in good contact with the base plate in the grooves, and since the heat dissipation capacity of the pure potting glue is weaker than the heat conduction of metal, the heat dissipation effect of the laser prepared by the above method is average.

[0037] Therefore, some existing technologies use a method of installing optical fibers without making grooves on the laser, as detailed in Chinese patent publication number CN110034483B. However, this solution is to fix the optical fiber to the laser by sticking tape, and then fix it with glue. In this solution, since air will inevitably remain in the sticking tape, it will greatly affect the heat dissipation of the optical fiber, which is very detrimental to the reliability of the fiber laser.

[0038] Therefore, the present disclosure provides a fiber processing method based on a fiber laser, such as Figure 1a As shown, including:

[0039] Step S100, first optical fiber fusion splicing. In this step, the optical fiber 300 and the first device are fusion spliced ​​together.

[0040] Step S200 , optical fiber coiling: Specifically, the optical fiber 300 is placed along the optical fiber installation groove of the second jig 200 to coil the optical fiber on the optical fiber installation grooves of the first jig and the second jig.

[0041] Step S300: performing a second optical fiber fusion splicing to fusion splice the rear end of the optical fiber to the second device.

[0042] Step S400: Fiber transfer to place the first fixture and the optical fiber on the first component of the laser.

[0043] Step S500: pre-fixing the optical fiber, so as to fix the local spiral part of the optical fiber on the first component by solidifying the liquid glue.

[0044] Step S600, removing the first jig, that is, separating the first jig from the local coiled portion of the optical fiber, so that the coiled portion of the optical fiber is fixed to the first component, and the first jig is separated from the first component.

[0045] Step S700, the optical fiber is re-fixed, and the coiled portion of the optical fiber is fixed to the first component by solidifying the liquid glue, wherein the liquid glue covers the entire coiled portion of the optical fiber.

[0046] It should be noted that if Figure 2 As shown, the optical fiber 300 as a whole includes a front end portion 310, a spiral portion 320 of the optical fiber, and a rear end portion 330 of the optical fiber, wherein the spiral portion 320 of the optical fiber is located between the front end portion 310 and the rear end portion 330, and is spirally wound on the first metallurgical tool 100 to form a spiral shape. Optionally, the spiral portion 320 of the optical fiber forms an Archimedean spiral. The optical fiber 300 can be a gain optical fiber 300 doped with other ions (such as rare earth ions).

[0047] It should be noted that the above scheme uses the second fixture 200 to achieve optical fiber winding and fusion of optical fiber with other devices, but in some embodiments, the second fixture 200 may not be used, and the optical fiber can be directly wound on the first fixture 100 with the same or similar function (or with the help of other structures) to complete the orderly and smooth winding of the optical fiber.

[0048] like Figure 1b The optical fiber processing method shown: In some optional embodiments, the optical fiber processing method includes: step S200, step S400, step S500, step S600 and step S700. More specifically, first, step S200 is implemented to coil the optical fiber on the first fixture. Secondly, step S400 is implemented to place the first fixture and the optical fiber on the first component of the laser. Furthermore, step S500 is performed to fix the local coiled portion of the optical fiber on the first component by solidifying the liquid glue. Subsequently, step S600 is implemented to remove the first fixture. Finally, step S700 is implemented to fix the coiled portion of the optical fiber on the first component by solidifying the liquid glue.

[0049] Alternatively, if Figure 3 As shown, when the optical fiber is transferred, the first jig is turned upside down to place the first jig 100 and the optical fiber 300 on the first component 400 of the laser, and the optical fiber 300 abuts against the first component 400, and the optical fiber 300 can move relative to the first component 400. More specifically, as Figure 3-5As shown, the first fixture 100 is formed with a first surface 110 and a second surface 120 opposite to each other, and the spiral portion 320 of the optical fiber is placed on the first surface 110 and is higher than the first surface 110. At the same time, a colloid with weak viscosity that can stick to the optical fiber 300 and can be easily removed is distributed on the first surface 110. Optionally, the colloid is an inverted high-temperature tape with the adhesive surface facing upward. Therefore, the optical fiber 300 can be fixed on the first surface 110 of the first fixture 100. However, no other connection structure is provided on the first component 400 to fix and install the optical fiber 300. Therefore, when the optical fiber 300 abuts against the first component 400, the optical fiber 300 can move relative to the first component 400. When the user puts the first fixture 100 upside down on the first component 400 but finds that the position of the optical fiber 300 does not meet the requirements, the first fixture 100 and the optical fiber 300 can be moved together to adjust the position of the optical fiber 300 on the first component 400. Furthermore, when the first jig 100 and the optical fiber 300 are placed on the first component 400 of the laser, the optical fiber 300 is directly in contact with the first component 400 and no gap is formed between the optical fiber 300 and the first component 400. Therefore, the user does not need to tap the optical fiber 300 to separate the optical fiber 300 from the first jig 100 and then install it on the first component 400, which is convenient for the user to perform multiple adjustments.

[0050] It should be noted that the first jig 100 is provided with a colloid to adhere the optical fiber 300. The main purpose of such a setting is to ensure the shape of the spiral portion 320 of the optical fiber. However, in the prior art, after the optical fiber 300 is separated from the first jig 100 and falls into the first assembly 400, the original shape cannot be effectively maintained, that is, the optical fiber 300 will be tangled in a disorderly manner, thereby affecting the heat dissipation effect of the optical fiber 300.

[0051] Regarding the solution of using the second fixture 200 to complete the fiber winding, as shown in FIG. Figure 6 As shown, the second jig 200 is formed with an optical fiber installation groove 210 to accommodate the optical fiber 300, and the second jig 200 is formed with a jig installation groove 220 to accommodate the first jig 100, that is, the first jig 100 can be installed in the second jig 200, and the optical fiber 300 is arranged in the optical fiber installation groove 210. Specifically, the bottom of the optical fiber installation groove 210 is higher than the bottom of the jig installation groove 220, so that after the first jig 100 is installed in the jig installation groove 220, the first surface 110 of the first jig 100 is flush with the bottom surface of the optical fiber installation groove 210, so that when the optical fiber 300 is installed along the first jig 100 and the second jig 200, the optical fiber 300 can be flushly arranged on the bottom surface of the optical fiber installation groove 210 and the first surface 110 of the first jig 100, that is, the part of the optical fiber 300 located in the first jig 100 and the part located in the second jig 200 are also basically flush.

[0052] More specifically, the solution of using the second fixture 200 to complete the fiber coiling further includes the following steps:

[0053] First, step S310, jig assembly, is performed to assemble the first jig and the second jig together.

[0054] Next, step S320 is implemented to arrange the optical fiber 300 along the guide channel until it reaches the entrance 211 of the optical fiber installation groove 210 of the second fixture 200;

[0055] Then, step S330 is implemented to coil the optical fiber 300 along the optical fiber installation groove 210 from the entrance 211 of the optical fiber installation groove 210 to the exit 212 of the optical fiber installation groove 210. Figure 2 Finally, the optical fiber 300 is wound on the first fixture 100 and the second fixture 200 .

[0056] It should be noted that after completing step S330, step S300 can be performed, that is, the rear end of the optical fiber 300 located outside the optical fiber installation groove 210 is connected to the second device. Among them, the second device can be a low-reflection grating, a cladding light filter or a reverse beam combiner. It should be noted that when the rear end of the optical fiber 300 is connected to the second device, the following processing work needs to be performed: cutting and cutting the outer skin according to the preset length to expose the core of the optical fiber 300, and then fusing, coating and other processes, and finally fusing the rear end of the optical fiber 300 to the second device.

[0057] In addition, if Figure 4 and Figure 5 As shown, the first jig 100 includes a middle portion 130, a front wing portion 140, a rear wing portion 150, a left wing portion 160 and a right wing portion 170. The front wing portion 140, the rear wing portion 150, the left wing portion 160 and the right wing portion 170 are respectively connected to the middle portion 130. Among them, the cross section of the middle portion 130 is similar to a circle, and the front wing portion 140, the rear wing portion 150, the left wing portion 160 and the right wing portion 170 are used to receive the optical fiber 300. The advantage of the above design is that the optical fiber 300 is received by the front wing portion 140, the rear wing portion 150, the left wing portion 160 and the right wing portion 170 respectively located on the four sides, so that the optical fiber 300 is more stably placed on the first jig 100 and is not easy to fall off from the first jig 100.

[0058] Moreover, the shape of the first metallurgical tool 100 can be adjusted according to the situation. Figure 4 and Figure 5 As shown, it is necessary to form a middle part 130, a front wing part 140, a rear wing part 150, a left wing part 160 and a right wing part 170. For example, three wings can be provided, evenly distributed on the outside of the middle part 130. Therefore, the present disclosure does not specifically limit the shape of the first metallurgy 100.

[0059] Optionally, the optical fiber installation groove 210 formed by the second fixture 200 is obtained based on the Archimedean spiral. The cross-section of the optical fiber installation groove 210 can be a square, and the side length of the square is greater than the diameter of the outermost layer (coating layer) of the optical fiber 300, and less than 2 times the diameter of the outermost layer (coating layer) of the optical fiber 300. The groove spacing in the radial direction is greater than 0.3mm, and the innermost fiber winding starting point is marked with a special shape. It should be noted that the cross-section of the optical fiber installation groove 210 can be triangular, circular, etc., and the present disclosure does not make specific restrictions.

[0060] First, in order to facilitate the placement of the optical fiber 300 in the optical fiber installation groove 210, the side length of the cross section of the optical fiber installation groove 210 is greater than the diameter of the optical fiber 300. And the groove spacing of the optical fiber installation groove is set to be greater than 0.3mm, ensuring that the interval between each circle of optical fiber 300 is large to avoid the thermal impact between each circle of optical fiber 300. Since the optical fiber 300 is prone to burnout at the fusion point between the optical fiber 300 and the first device, the first metallurgical tool 100 is optionally provided with a fusion point protection structure 700, which can be prepared from a heat dissipation material, so as to improve the heat dissipation effect of the fusion point through the fusion point protection structure 700, so as to protect the fusion point from being easily damaged by high temperature during the operation of the laser. More specifically, the following processing method is also included when winding the optical fiber: the fusion point between the optical fiber 300 and the first device is placed on the fusion point protection structure 700 on the first fixture 100, and then the non-fusion-connected optical fiber portion is routed along the optical fiber installation groove 210 to place the optical fiber 300 on the first fixture 100 and the second fixture 200.

[0061] In addition, it should be noted that the fusion splicing of the optical fiber and the first device is not required in all cases. Therefore, in some embodiments, the first tool may not be provided with a fusion splice protection structure to protect the fusion splice between the optical fiber and the first device.

[0062] Moreover, the fusion point protection structure 700 is located inside the optical fiber installation groove 210, which can facilitate the optical fiber 300 to be coiled from the inside of the optical fiber installation groove 210. Of course, in some embodiments, the optical fiber 300 can also be coiled from the outside of the optical fiber installation groove 210 to the inside.

[0063] Optionally, when the optical fiber is coiled, the first device and the front end portion 310 of the optical fiber are placed in the guide channel of the first mold 100 and the coiled portion 320 of the optical fiber is placed on the first surface 110 of the first mold 100, so that when the optical fiber is transferred, the front end portion 310 of the optical fiber, the coiled portion 320 of the optical fiber and the first component 400 of the laser are placed in sequence from top to bottom.

[0064] Specifically, the guide channel is divided into a first guide channel 181 and a second guide channel 182, and the first guide channel 181 and the second guide channel 182 are connected through the fusion point protection structure 700. One end of the first guide channel 181 is connected to the fusion point channel 720 in the fusion point protection structure 700, the other end of the first guide channel 181 is connected to the outside, and one end of the second guide channel 182 is connected to the fusion point channel 720 in the fusion point protection structure 700. The other end of the second guide channel 182 extends toward the entrance 211 of the optical fiber installation groove 210, but may not extend to the entrance 211 of the optical fiber installation groove 210. Therefore, the first device can be placed in the first guide channel 181, and the front end portion 310 of the optical fiber can be placed in the second guide channel 182, and the fusion point between the first device and the front end portion 310 of the optical fiber can be placed in the fusion point channel 720 of the fusion point protection structure 700.

[0065] In addition, since the guide channel is formed by being recessed downward on the first surface 110, the optical fiber 300 (i.e., the front end portion 310 of the optical fiber) located therein is located below the spiral portion 320 of the optical fiber. However, after the first jig 100 is turned upside down to press the optical fiber 300 against the first component 400, the spiral portion 320 of the optical fiber is located below the front end portion 310 of the optical fiber and abuts against the first component 400, so that the front end portion 310 of the optical fiber, the spiral portion 320 of the optical fiber and the first component 400 of the laser are placed in sequence from top to bottom. Figure 2 and Figure 3 It can be seen that the spiral portion 320 of the optical fiber can now obtain better heat dissipation, and will not be lifted up due to the front end portion 310 of the optical fiber being located below it, thereby affecting its arrangement.

[0066] Optionally, the first surface 110 of the first metallurgical tool 100 is recessed downward to form a first mounting groove 190 for mounting the weld point protection structure 700, and the weld point protection structure 700 is detachably connected to the first metallurgical tool 100. Specifically, the first mounting groove 190 is a through groove, and abutment portions 191 are provided on both sides of the first mounting groove 190 to prevent the weld point protection structure 700 from detaching from the first mounting groove 190 in the direction from the first surface 110 to the second surface 120. In addition, the weld point protection structure 700 is provided with a threaded hole 710, and the abutment portion 191 is formed with a through hole 1911, and a screw can pass through the abutment portion 191 to be threadedly connected to the threaded hole 710 of the weld point protection structure 700, so that the weld point protection structure 700 is detachably connected to the first metallurgical tool 100. In addition, as Figure 8As shown, a second mounting groove 230 is formed on the second fixture 200, and the second mounting groove 230 is a through groove. When the first fixture 100 is installed on the second fixture 200, the position of the first mounting groove 190 corresponds to the position of the second mounting groove 230. Therefore, the user can observe the fusion point protection structure 700 from the side of the second fixture 200. And because part of the area in the fusion point channel 720 of the fusion point protection structure 700 is also through, the user can directly observe the optical fiber 300 in the fusion point protection structure 700 from the side of the second fixture 200, as shown in FIG. Figure 8 shown.

[0067] Optionally, a colloid is provided on the first jig 100 to adhere the optical fiber 300, and the viscosity of the colloid is lower than that of the liquid glue. The colloid on the first jig 100 may be an inverted high temperature resistant tape with the glue side facing upward. The viscosity of the colloid is made lower than that of the liquid glue to prevent the optical fiber 300 from being fixed on the first jig 100 and unable to be detached from the first jig 100 when the first jig 100 is buckled on the first component 400 to fix the spiral portion 320 of the optical fiber on the first component 400 through the liquid glue.

[0068] In addition, the surface of the second fixture 200 is recessed downward to form a receiving groove, in which the optical fiber 300 and the first fixture 100 can be placed.

[0069] In addition, the present disclosure also provides a laser, and in the process of preparing the laser, the above-mentioned fiber processing method based on the fiber laser is adopted. More specifically, the first component 400 is a part of the laser, and can be a part of the water cooling structure of the laser, and can be optionally an upper plate of the water cooling structure. After the optical fiber 300 is smoothly and effectively transferred to the first component 400 according to the above method, the subsequent assembly of other parts of the laser can be continued to prepare the laser.

[0070] When processing the optical fiber, first, step S100 is implemented to process the optical fiber 300 and the first device, including cutting, slicing, fusing, coating, etc. according to a preset length.

[0071] Next, step S200 is performed to coil the optical fiber.

[0072] Specifically, to implement step S200, first, the first jig and the second jig need to be assembled together. Next, the fused optical fiber 300 and the fusion point of the first device need to be placed in the fusion point channel 720 of the fusion point protection structure 700, and the fusion point is fixed in the fusion point protection structure 700 by UV glue. Then, the front end portion 310 of the optical fiber is placed along the second guide channel 182, and the first device is placed along the first guide channel 181. Then, the optical fiber 300 is coiled from the inside to the outside along the optical fiber installation groove 210 to form the coiled portion of the optical fiber 300. At this time, the coiled portion of the optical fiber 300 is adhered to the first jig 100 by a colloid (high temperature resistant tape), and the coiled portion of the optical fiber 300 is separated from each other in the radial direction.

[0073] Subsequently, step S300 is performed to perform a second optical fiber fusion splicing to fusion splice the rear end of the optical fiber 300 with the second device.

[0074] Next, the step S400 of optical fiber transfer is performed, the first fixture 100, the fusion point protection structure 700 and the optical fiber 300 are moved together, and then the three are buckled onto the first assembly 400. At this time, the first assembly 400, the spiral portion 320 of the optical fiber and the first fixture 100 are connected in sequence from bottom to top.

[0075] Then, step S500 is performed to fix the local spiral portion 320 of the optical fiber on the first component 400 by solidifying the liquid glue. Specifically, the part of the spiral portion 320 of the optical fiber exposed from the first mold 100 is partially encapsulated by solidifying the liquid glue, so that the spiral portion 320 of the optical fiber is fixed on the first component 400. For details, see Fig. 9 In some embodiments, the optical fiber 300 is partially potted by pouring glue 500 four times. Glue is also a type of liquid glue. Liquid glue is in liquid state before use, but becomes solid after solidification, so as to achieve fixation. The liquid glue of this embodiment is preferably a thermally conductive potting glue, which is applied to the optical fiber 300 and the first component 400, and the optical fiber 300 and the first component 400 can be fixed together after solidification.

[0076] Next, the first metallurgical tool 100 is removed in step S600, so that the first metallurgical tool 100 is separated from the optical fiber 300. Fig.10 When removing the first metallurgy 100 , the screws used to connect the first metallurgy 100 and the welding point protection structure 700 can be removed first, and then the first metallurgy 100 can be lifted up.

[0077] Finally, step S700 is performed to seal the spiral portion 320 of the optical fiber and the fusion point protection structure 700 with liquid glue. Fig.11As shown, the spiral portion 320 of the optical fiber and the fusion point protection structure 700 are completely covered by the liquid glue, avoiding the residual air, and enabling the fusion point protection structure 700 and the spiral portion 320 of the entire optical fiber to be effectively fixed on the first component 400. Specifically, the present application performs comprehensive potting and fixing of the optical fiber 300 by means of the surface glue 600. It should be noted that the liquid glue used for the point glue 500 and the surface glue 600 is the same, but has different names due to the different sizes of the laying areas.

[0078] The advantage of the above scheme is that the liquid glue used for the dispensing glue 500 and the surface glue 600 of the present application is preferably a thermal conductive potting glue. By adopting the liquid glue fixing method twice, the multi-layer coiled optical fiber part of the optical fiber 300 and the optical fiber 300 and the first component 400 can be effectively sealed and bonded together through the thermal conductive potting glue, which can effectively avoid the influence of residual air on the heat dissipation of the optical fiber and ensure a better heat dissipation effect.

[0079] Secondly, since the optical fiber 300 is located on the first surface 110 of the first jig 100, when the first jig 100 and the optical fiber 300 are turned upside down to transfer the optical fiber 300 to the first component 400 in this solution, the optical fiber 300 directly abuts against the first component 400 and can move relative to the first component 400, that is, the optical fiber 300 and the first component 400 are directly and movably fixed on the first component 400, which can effectively adjust the position of the optical fiber 300 on the first component 400, and there is no need to tap or use other methods to detach the optical fiber 300 from the first jig 100.

[0080] In addition, this solution not only pots the optical fiber 300 (liquid glue potting), but also pots the fusion point protection structure 700, effectively ensuring the heat dissipation effect between the optical fiber 300, the fusion point protection structure 700 and the fusion point.
