Description

Technical Field

[0001] This application relates to the technical field of laser devices, and particularly to a light stripper and a laser device. Background Art

[0002] With the demand for high-power lasers, pump light is introduced into the fiber cladding. While the pump light propagates in the inner cladding of the active fiber, it is continuously stripped by the core to achieve laser enhancement. However, due to reasons such as the length limitation of the fiber, the pump light cannot be completely stripped by the core. At the same time, during the process of the fiber transmitting laser, a small part of the light also enters the cladding and propagates in the cladding, forming cladding light. The existence of cladding light will reduce the quality of the laser output from the fiber.

[0003] In the related art, generally, the laser transmission conditions of the fiber cladding are destroyed by means such as corrosion to leak out the cladding light to achieve cladding light stripping. However, the heat generated by stripping the cladding light accumulates around the fiber, resulting in a high temperature on the fiber surface and reducing the service life of the fiber.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0041] It should be understood that considering the factors of actual tolerances, the term "vertical" in the technical solution of the present application is used to describe the ideal state between two components. In the actual production or use state, there may be a state approximately vertical between the two components. The two components described as "vertical" may not be absolutely straight lines or planes, and may also be approximately straight lines or planes. From a macroscopic perspective, as long as the overall extension direction is a straight line or a plane, the components can be considered "straight lines" or "planes". It should be noted that the "-" and "~" in the present application should be understood as including the numerical values at their endpoints. For example, if a certain value is between 1-10, it should be understood that the numerical value is greater than or equal to 1 and less than or equal to 10; if it is between 1~10, it should be understood that the numerical value is greater than or equal to 1 and less than or equal to 10.

[0042] High-power fiber laser devices have the advantages of good beam quality, high efficiency, compact structure, and good heat dissipation, and have developed rapidly in recent years. In order to achieve the output of high-power laser, double-clad doped fiber is usually used as the active fiber. While the pump light propagates in the inner cladding of the active fiber, it is continuously absorbed by the core. Under the condition of resonator feedback, laser is generated.

[0043] However, due to reasons such as the limited length of the active fiber and the existence of helical light in the cladding, the pump light cannot be completely absorbed by the core, resulting in residual pump light in the cladding. At the same time, imperfect splicing between fibers and local defects of the fiber itself will also cause some of the signal light transmitted in the fiber core to leak into the cladding. These two kinds of light propagate in the cladding to form cladding light. The existence of cladding light makes the laser energy distribution not concentrated, seriously affecting the beam quality of the laser, and thus affecting the subsequent laser beam combination and laser processing effects. In high-power fiber laser devices, if the cladding light power is too large, it will even damage the subsequent devices, thereby reducing the service life of the laser device.

[0044] In the related art, in the existing preparation technology of high-power fiber mode strippers, more often after removing the outer cladding of the double-clad fiber, a single or different refractive index organic glue is coated on the surface of the inner cladding along the single section or segmented section of the fiber to destroy the original total reflection condition and form a cladding light stripping section, so that the cladding light can leak into the external space. However, the inventor found that since the organic glue is an organic polymer, the temperature it can withstand for a long time is limited. When used under high-temperature conditions for a long time, it may cause changes in the properties of the glue, an increase in light absorption, and with the increase in temperature, the light absorption will be further aggravated, seriously affecting the stability of high-power fiber laser devices.

[0045] Further, it should be noted that in this application, the cladding section, the cladding light stripping section, and the coating section of the optical fiber are mentioned, which are optical fiber sections with different structures. Among them, the cladding light stripping section has been described above and will not be elaborated here. That is, referring to the description of the cladding light stripping section above, the cladding section is the cladding section without coating a single or different refractive index organic glue on the inner cladding surface. This cladding section will not leak cladding light and has no outer cladding. Among them, the coating section is the optical fiber section formed by coating a protective layer on the outer surface of the cladding section. This protective layer is also called the outer cladding, that is, the coating section is the optical fiber section with an outer cladding.

[0046] On this basis, this application provides a light stripper and a laser device. By setting a light stripper and a laser device with a separation part, the cladding light is separated and absorbed to achieve stripping, avoiding the concentration of cladding light on the outer wall of the cladding of the optical fiber, thereby reducing the working temperature of the organic glue, preventing the optical fiber from being burned due to high temperature, prolonging the service life of the high-power laser device, and improving its stability.

[0047] Specifically, referring to Figure 1 , this embodiment provides a light stripper 1, including: a light stripping body 10. A receiving channel 100 for receiving the optical fiber 3 is provided on the light stripping body 10. A separation part 1000 is provided in the receiving channel 100. The separation part 1000 is arranged corresponding to the cladding light stripping section 30 of the optical fiber 3, and is used for separating and stripping the cladding light leaking from the cladding light stripping section 30.

[0048] It can be understood that in the implementation scheme of this application, the light stripper 1 is used for the optical fiber 3 capable of leaking cladding light from the outer wall of the cladding, that is, the optical fiber 3 with a cladding light stripping section 30.

[0049] Specifically, the separation part 1000 is mainly used to separate and strip the cladding light leaking from the cladding light stripping section 30. Among them, the specific structure, the number of settings, and the setting position of the separation part 1000 are not specifically limited in this application.

[0050] Exemplarily, in one implementation scheme of this application, the structure of the separation part 1000 can be depressions or protrusions arranged at intervals on the inner wall of the receiving channel 100.

[0051] Exemplarily, in one implementation scheme of this application, the separation part 1000 covers the entire inner wall of the receiving channel 100 to achieve separating and stripping the cladding light leaking from the outer wall of the cladding, and improving the versatility of the light stripper 1 relative to the optical fiber 3.

[0052] Specifically, referring to Figure 1 and Figure 2 , in the implementation scheme of this application, the shape of the receiving channel 100 corresponding to the optical fiber 3 is generally an annular receiving channel.

[0053] Specifically, refer to Figure 2 and Figure 3 In one embodiment of the present application, the separation part 1000 is located in the first channel segment 1001 of the accommodation channel 100, and the first channel segment 1001 is used to accommodate the cladding stripping segment 30 of the optical fiber 3.

[0054] That is, it can be understood that the separation part 1000 is arranged corresponding to the cladding stripping segment 30 of the optical fiber 3. It can be understood that if there are multiple cladding stripping segments 30 arranged at intervals in the optical fiber 3, then there are also multiple first channel segments 1001 arranged corresponding to the cladding stripping segments 30; in the actual installation process, the separation part 1000 is arranged corresponding to the cladding stripping segment 30 to separate and strip the cladding light leaking from the cladding stripping segment 30.

[0055] In the embodiment of the present application, by arranging the separation part 1000 in the first channel segment 1001, the manufacturing complexity of the separation part 1000 is reduced, and by arranging the other areas of the channel accommodation cavity except the first channel segment 1001 to be in contact with the optical fiber 3, the limiting effect of the optical fiber 3 is improved, and the optical fiber 3 is prevented from shifting.

[0056] It can be understood that in some other embodiments of the present application, the other areas of the channel accommodation cavity except the first channel segment 1001 may not be in contact with the optical fiber 3, and specific applications are not specifically limited.

[0057] In this embodiment, by arranging the accommodation channel 100 for accommodating the optical fiber 3, while limiting the optical fiber 3, a separation part 1000 is arranged in the accommodation channel 100, and the separation part 1000 is arranged corresponding to the cladding stripping segment 30 of the optical fiber 3. While realizing the stripping of the cladding light leaking from the outer wall of the cladding, the cladding light is further separated by the separation part 1000 to prevent the cladding light from converging on the surface of the optical fiber 3, and at the same time, the cladding light is separated into multiple parts for stripping, which can effectively reduce the heat generated by the convergence of the cladding light, greatly improve the cladding light stripping efficiency, and further improve the service life of the stripping device 1 and the optical fiber 3.

[0058] Specifically, in one embodiment of the present application, the separation part 1000 is a grid structure. By arranging the grid structure, the cladding light is distributed into different spaces for stripping to avoid light concentration.

[0059] It can be understood that the embodiment of the present application does not limit the specific shape of the grid structure.

[0060] Specifically, refer to Figure 3 and Figure 4, in one embodiment of the present application, the first channel section 1001 is used to accommodate the cladding light stripping section 30 of the optical fiber 3, and the separating part 1000 is a groove structure arranged at intervals on the inner wall of the first channel section 1001.

[0061] Specifically, based on any of the above embodiments, the separating part 1000 is a groove structure, which can greatly increase the thermal stripping area of the separating part 1000 and improve the stripping efficiency.

[0062] Specifically, continuing to refer to Figure 2 and Figure 3 , in the embodiment of the present application, the groove structure is an inclined groove structure. Specifically, the groove structure includes a groove opening 10001 and a groove wall 10002, and the groove wall 10002 is inclined relative to the groove opening 10001.

[0063] Specifically, in this solution, by setting the inclined groove structure as the separating part 1000, it is avoided that the leaked cladding light is reflected back into the optical fiber cladding at the separating part 1000, affecting the optical transmission of the optical fiber 3.

[0064] Specifically, in one embodiment of the present application, a fixing structure 101 is arranged in the accommodating channel 100 for fixing the optical fiber 3 in the accommodating channel 100.

[0065] In this solution, by arranging the fixing structure 101 in the accommodating channel 100, the displacement of the optical fiber 3 is avoided, the installation stability of the optical fiber 3 is enhanced, and damages such as breakage of the optical fiber 3 are avoided.

[0066] Specifically, refer to Figure 2 , Figure 3 , based on any of the above embodiments, the annular accommodating channel further includes a second channel section 1002, the second channel section 1002 is used to accommodate the cladding section 31 of the optical fiber 3, and a fixing structure 101 is arranged in the annular accommodating channel for fixing the optical fiber 3 in the annular accommodating channel.

[0067] Specifically, the fixing structure 101 includes a low-refractive-index glue, and the low-refractive-index glue is arranged in the second channel section 1002, and the second channel section 1002 is used to limit the optical fiber 3.

[0068] In the embodiment of the present application, by arranging the fixing structure 101 to include a low-refractive-index glue and arranging the low-refractive-index glue in the second channel section 1002, while fixing the optical fiber 3, the pump light in the leaked cladding light is transmitted to the outside through the low-refractive-index glue, further avoiding the thermal damage to the cladding caused by the convergence of the cladding light on the cladding surface and improving the cladding light stripping efficiency.

[0069] Based on any of the above embodiments, the low-refractive-index glue is located on one side of the separation part 1000, the low-refractive-index glue is located on the side far from the input end of the optical fiber 3, and the separation part 1000 is located on the side close to the input end of the optical fiber 3.

[0070] Specifically, in the embodiment of the present application, by arranging the low-refractive-index glue on one side of the separation part 1000, and the separation part 1000 is located on the side close to the input end of the optical fiber 3 in the first channel section 1001, so that the cladding light leaked in the stripping layer stripping section is first separated and stripped by the separation part 1000, and then further stripped again by the low-refractive-index glue. Since the separation part 1000 has stripped part or all of the light, that is, the remaining cladding light reaching the low-refractive-index glue is less. Stripping the remaining cladding light by the low-refractive-index glue position will not cause a large amount of heat accumulation, thereby realizing the control of reducing the working temperature of the low-refractive-index glue position and avoiding the change of the glue properties, resulting in the reduction of the performance of the low-refractive-index glue. And in this solution, by arranging the low-refractive-index glue in the second channel section 1002, the installation stability between the separation part 1000 and the cladding light stripping section 30 of the optical fiber 3 is ensured, thereby ensuring the light stripping effect and the heat dissipation effect.

[0071] Specifically, in one embodiment of the present application, the stripping body 10 is a split structure, specifically including a first symmetric structure and a second symmetric structure stacked along the channel axis of the accommodating channel 100. The first symmetric structure and the second symmetric structure are tightened by screws to form the stripping body 10 of the accommodating channel 100.

[0072] In the embodiment of the present application, by setting the stripping body 10 as a split structure, when the first symmetric structure and the second symmetric structure are opened in half, it is convenient to place the optical fiber 3 in the accommodating cavity and ensure the accurate installation position of the optical fiber 3.

[0073] In the embodiment of the application, see Figure 3 and Figure 4 , the optical fiber 3 installed by the stripper includes an optical fiber input head 33 and an optical fiber body connected to the optical fiber input head 33. The optical fiber body includes a cladding section 31, a cladding light stripping section 30, and a coated section 32.

[0074] Specifically, in combination with reference to Figure 2 and 3, specifically, in this embodiment, the annular accommodation channel further includes a third channel section 1003 and a fourth channel section 1004; the third channel section 1003 is used to accommodate the coated section 32 of the optical fiber 3; the fourth channel section 1004 is used to accommodate the optical fiber input head 33, wherein, an optical fiber input head protection ring 12 is provided in the fourth channel section 1004 for protecting the optical fiber input head 33; one end of the fourth channel section 1004 is provided with a first opening 1005, the other end of the fourth channel section 1004 is connected to the second channel section 1002, the first channel section 1001 is arranged between two second channel sections 1002, one end of the third channel section 1003 is connected to the second channel section 1002, the other end of the third channel section 1003 is provided with a second opening 1006, and the first opening 1005 and the second opening 1006 communicate to form the annular accommodation channel.

[0075] Specifically, the optical fiber input head protection ring 12 is a metal gasket, a part of the optical fiber input head 33 is embedded in the fourth channel 1004, and the optical fiber input head protection ring 12 is clamped between the inner wall of the fourth channel 1004 and the outer wall of the optical fiber input head 33.

[0076] Specifically, referring to Figure 2 and Figure 3 it can be seen that in the embodiment of this application, there are two second channel sections 1002. Specifically, the fourth channel section 1004, one of the second channel sections 1002, the first channel section 1001, the other second channel section 1002, and the third channel section 1003 are connected in sequence to form the annular accommodation channel, and the channel widths between the fourth channel section 1004, one of the second channel sections 1002, the first channel section 1001, the other second channel section 1002, and the third channel section 1003 are also different. Among them, the third channel section 1003 is in contact with the outer wall of the coated section 32 of the optical fiber 3 to achieve positioning, that is, the channel width of the third channel section 1003 is set corresponding to the width of the coated section 32 of the optical fiber 3, the fourth channel section 1004 is used to position the optical fiber input head 33 of the optical fiber 3, that is, the fourth channel section 1004 is set corresponding to the width of the optical fiber input head 33. Among them, the second channel section 1002 and the first channel section 1001 are respectively arranged at intervals from the cladding section 31 and the cladding stripping section 30, that is, the channel width of the second channel section 1002 is greater than the width of the cladding section 31, and the channel width of the first channel section 1001 is greater than the width of the cladding stripping section 30.

[0077] It is understandable that in the embodiments of the present application, two cladding segments 31 are correspondingly provided for the optical fiber segment. One of the cladding segments 31 is disposed between the coating segment 32 and the cladding light stripping segment 30, and the other cladding segment 31 is disposed between the optical fiber input head 33 and the cladding light stripping segment 30. Moreover, the other cladding segment 32 is connected to the optical fiber input head 33. The laser is input through the optical fiber input head 33 and sequentially passes through the cladding segment 31, the cladding light stripping segment 30, the cladding segment 31, and the coating segment 32. When passing through the cladding light stripping segment 30, the cladding light leaks out and is separated and absorbed by the separating portion 1000.

[0078] In this solution, by providing the cladding segment 31 between the coating segment 32 and the cladding light stripping segment 30 and providing a low-refractive-index adhesive corresponding to the cladding segment 32 to further absorb the cladding light, it is possible to prevent the heat of the cladding light from being transmitted to the coating segment, damaging the coating of the coating segment, and affecting the service life of the optical fiber.

[0079] Specifically, in some embodiments of the present application, the stripper 1 can be assembled on a device with a laser output function through the mounting portion 102. The mounting portion 102 can be provided with a limiting card slot or mounting bolts.

[0080] In the embodiments of the present application, referring to Figure 1 and Figure 6 , the mounting portion 102 is a protruding mounting platform, and the mounting platform is provided with mounting bolt holes for realizing the assembly with other devices.

[0081] Specifically, in the embodiments of the present application, the optical fiber input head 33 is a glass head.

[0082] Specifically, in one embodiment of the present application, the stripper 1 further includes a locking buckle 13 and a sleeve 14;

[0083] The locking buckle 13 is sleeved on the second open end 105 of the stripping body 10. The second open end 105 includes a second opening 1006. The locking buckle 13 is used to limit the optical fiber 3 located at the second open end 105. The sleeve 14 is disposed in the third channel 1003 and is used to sleeve on the coating segment 32.

[0084] Specifically, referring to Figure 3 and Figure 5 , in some embodiments of the present application, the outer wall of the stripping body 10 corresponding to the installation of the locking buckle 13 is provided with an installation thread 103, and the inner wall of the locking buckle 13 has a matching internal thread for realizing the assembly with the stripping body 10. The assembly is simple and has high stability.

[0085] This solution improves the stability of the installation of the optical fiber 3 by providing the locking buckle 13 and the sleeve 14.

[0086] Further, based on any of the above embodiments, with reference to Figure 7 , the present application further provides a laser device, which includes an optical fiber 3. The optical fiber 3 includes a cladding light stripping section 30, a stripper 1 as in any of the above embodiments, and a laser body 2. The stripper 1 is used to separate and strip the cladding light leaking from the cladding light stripping section 30. The stripping body 10 of the stripper 1 is assembled at the laser output end of the laser body 2 for outputting laser into the optical fiber 3.

[0087] Specifically, with further reference to Figure 3 In the embodiment of the present application, the optical fiber 3 includes an optical fiber input head 33 and an optical fiber body connected to the optical fiber input head 33; the optical fiber body includes a cladding section 31, a cladding light stripping section 30, and a coating section 32.

[0088] Corresponding to the above embodiment, in the present application, two cladding sections 31 are also provided corresponding to the optical fiber section. One of the cladding sections 31 is disposed between the coating section 32 and the cladding light stripping section 30, and the other cladding section 31 is disposed between the optical fiber input head 33 and the cladding light stripping section 30, and the other coating section 32 is connected to the optical fiber input head 33. The laser is input through the optical fiber input head 33 and sequentially passes through the cladding section 31, the cladding light stripping section 30, the cladding section 31, and the coating section 32. When passing through the cladding light stripping section 30, the cladding light leaks out and is separated and absorbed by the separating portion 1000 to achieve stripping.

[0089] Specifically, with reference to Figure 8 , in this solution, an installation groove 20 is provided at the laser output end. The first open end 104 of the stripping body 10 is embedded in the installation groove 20. Among them, the first open end 104 includes a first opening 1005 of the accommodating channel 100, and a light-transmitting hole 200 is provided at the bottom of the installation groove 20 for providing a laser path to transmit the laser output by the laser body 2 into the optical fiber 3.

[0090] Specifically, in this solution, during specific assembly, the first open end 104 of the stripping body 10 is embedded in the installation groove 20. One end of the optical fiber input head 33 is disposed in the accommodating channel 100, and the other end of the optical fiber input head 33 is located in the installation groove 20;

[0091] A light-transmitting hole 200 is provided at the bottom of the installation groove 20 for providing a laser light source path to output the light through the optical fiber input head 33 into the optical fiber 3.

[0092] Specifically, in the implementation solution of the present application, the optical fiber 3 is installed in the accommodation channel 100, and the input end of the optical fiber 3 is arranged at the first opening end 104 of the accommodation channel 100 and connected to the optical fiber input head 33. By providing a light-transmitting hole 200 at the bottom of the installation groove 20, the laser can be input into the optical fiber input head 33 through the light-transmitting hole 200.
