Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fiber lasers, in particular to a cladding light stripping method, device, equipment and storage medium. BACKGROUND

[0002] When the fiber laser is used for process processing, the laser works for a long time, and the cladding light, as the residual light in the double-clad fiber, needs to be filtered out. The cladding light will affect the beam quality of the final output laser, and will have a great impact on the equipment at the output end of the fiber laser (such as cutting heads and welding heads, etc.), and the higher the power, the more cladding light energy in the optical system. These cladding lights will directly affect the safe operation of the high-power laser, so they need to be stripped. At present, the cladding light stripper (CMS) is often used to process cladding light, but CMS is often used to strip cladding light with large power. When processing low-energy cladding light, CMS is not economical, in addition to increasing the cost, it also increases the risk of the quality of the device itself and the risk caused by the fusion of the device fiber. Therefore, how to economically and effectively strip the cladding light and ensure the safe operation of the fiber laser has become a problem to be solved.

[0052] It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

[0053] Referring to Figure 1 , Figure 1 The schematic structural diagram of the cladding light stripping device related to the hardware running environment of the embodiment of the present application is shown in the figure.

[0054] As Figure 1 shown, the cladding light stripping device can include a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.

[0055] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the cladding light stripping device, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0056] As Figure 1 shown, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a cladding light stripping program.

[0057] In the cladding light stripping device shown in Figure 1 , the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the cladding light stripping device of the present application can be arranged in the cladding light stripping device, and the cladding light stripping device calls the cladding light stripping program stored in the memory 1005 through the processor 1001, and executes the cladding light stripping method provided by the embodiment of the present application.

[0058] Based on the above cladding light stripping device, the embodiment of the present application provides a cladding light stripping method, which refers to Figure 2 , Figure 2 The flowchart of the first embodiment of the cladding light stripping method of the present application.

[0059] In this embodiment, the cladding light stripping method comprises the following steps:

[0060] Step S10: obtaining energy information and divergence angle information of the cladding light to be stripped;

[0061] It should be noted that the execution subject of the present embodiment can be a fiber laser and its supporting equipment, and the method of the present embodiment can be applied to the cladding light generated during the manufacture of the fiber laser.

[0062] It can be understood that the cladding light to be stripped refers to the “unfriendly” residual light existing in the double-clad fiber during the normal operation of the fiber laser during process processing, which can specifically include the cladding light generated by each component in the forward transmission fiber laser, the cladding light generated by fiber fusion, and the return light generated by processing high-reflection materials in the reverse direction. The present embodiment needs to filter out the cladding light to be stripped.

[0063] It should be understood that the cladding light to be stripped will be transmitted in the fiber laser, and the energy information refers to the energy corresponding to each position in the transmission path of the fiber laser, i.e., the size of the cladding light energy, and the divergence angle information refers to the divergence angle corresponding to each position in the transmission path of the fiber laser. The energy information and the divergence angle information corresponding to each position of the cladding light to be stripped in the fiber laser can be different.

[0064] Step S20: determining the target glue required by the cladding light to be stripped at the target position according to the energy information and the divergence angle information;

[0065] It can be understood that the target position refers to the position of the cladding light to be stripped on the light wave transmission path in the fiber laser, which can specifically include the starting position of the cladding light to be stripped, the fusion point fiber position, the fiber fusion position, the output port position, etc., and can also include other positions, which are not limited in the present embodiment.

[0066] It should be understood that the target glue refers to UV curing glue, which can specifically include high-refractive UV curing glue and low-refractive UV curing glue, and the amount of glue can also be determined.

[0067] In a specific implementation, the target glue type and the target glue amount of the target glue required by the cladding light to be stripped at each target position can be different, and can be determined according to the energy information and the divergence angle information of the target position. For example, the greater the energy and the greater the divergence angle, the more the high-refractive glue amount required can be, which can be determined according to actual conditions, and the embodiment does not make a specific limitation in this regard.

[0068] Step S30: stripping the cladding light to be stripped at the corresponding target position by the target glue.

[0069] It can be understood that the cladding light to be stripped at each target position can be stripped by the target glue corresponding to the target position, so that the amount of the cladding light in the fiber laser can be reduced, and the optical path device in the fiber laser can be stabilized, and the safe operation of the fiber laser can be ensured.

[0070] In the embodiment, the energy information and the divergence angle information of the cladding light to be stripped are acquired, and then the target glue required by the cladding light to be stripped at the target position is determined according to the energy information and the divergence angle information, and the cladding light to be stripped at the corresponding target position is stripped by the target glue. In the embodiment, the target glue required by the cladding light to be stripped at the target position is determined according to the energy information and the divergence angle information, and the cladding light to be stripped at the corresponding target position is stripped by the target glue. The cladding light can be effectively stripped, and the cladding light to be stripped at each target position can be stripped. The above-mentioned method can be used in different positions in the optical path of the fiber laser. Compared with the existing cladding light stripper for processing the cladding light, the above-mentioned method can effectively strip the low-power cladding light, is flexible and simple, reduces the number of cladding light strippers, thereby reducing the cost, and can stabilize the optical path device in the fiber laser and ensure the safe operation of the fiber laser.

[0071] Reference Figure 3 , Figure 3 FIG. 2 is a flowchart of a cladding light stripping method according to a second embodiment of the present application.

[0072] Based on the first embodiment, in the embodiment, the step S20 includes:

[0073] Step S201: acquiring optical fiber type information corresponding to an optical fiber through which the cladding light to be stripped passes;

[0074] It should be noted that the cladding light to be stripped passes through a plurality of optical fibers when being transmitted in the fiber laser, and the optical fiber type information refers to the type corresponding to each optical fiber in the fiber laser.

[0075] Step S202: acquiring a transmission direction of the cladding light to be stripped, and determining a target position according to the transmission direction;

[0076] It can be understood that the transmission direction can include forward transmission and reverse transmission, the forward transmission refers to the transmission of the to-be-stripped cladding light from the pump source to the direction of the generated laser output in the fiber laser, and the reverse transmission refers to the reverse transmission of the to-be-stripped cladding light from the direction of the laser output.

[0077] It should be understood that the order of the target positions through which the to-be-stripped cladding light passes is different in different transmission directions, for example, in forward transmission, the target positions through which the to-be-stripped cladding light passes are in turn: the stripping port position, the fusion splice optical fiber, the optical fiber fusion splice, the fusion splice optical fiber, and the reverse stripping port position; in reverse transmission, the target positions through which the to-be-stripped cladding light passes are in turn: the reverse stripping port position, the fusion splice optical fiber, the optical fiber fusion splice, the fusion splice optical fiber, and the stripping port position.

[0078] Further, in order to determine the target positions corresponding to different transmission directions, in the embodiment, the step S202 includes: acquiring the transmission direction of the to-be-stripped cladding light; when the transmission direction is forward transmission, the target positions are in turn: the stripping port position, the first segment of the fusion splice optical fiber, the first optical fiber fusion splice, the second segment of the fusion splice optical fiber, the reverse stripping port position, …, the stripping port position, the (2M-1)th segment of the fusion splice optical fiber, the Mth optical fiber fusion splice, the 2Mth segment of the fusion splice optical fiber, and the reverse stripping port position, M is a natural number; when the transmission direction is reverse transmission, the target positions are in turn: the reverse stripping port position, the 2Nth segment of the fusion splice optical fiber, the Nth optical fiber fusion splice, the (2N-1)th segment of the fusion splice optical fiber, and the stripping port position, …, the reverse stripping port position, the second segment of the fusion splice optical fiber, the first optical fiber fusion splice, the first segment of the fusion splice optical fiber, and the stripping port position.

[0079] It can be understood that the stripping port position refers to the boundary position at which the optical fiber is stripped of the outer coating in the fusion splice of the fiber laser, the fusion splice refers to the entire region of the two segments of the optical fiber after the fusion splice, the fusion splice refers to the junction of the two segments of the optical fiber after the fusion splice, and the reverse stripping port position refers to the position symmetrical to the forward stripping port in the fiber laser.

[0080] It should be understood that the stripping port position refers to the boundary position at which the optical fiber is stripped of the outer coating in the fusion splice of the fiber laser, the fusion splice refers to the entire region of the two segments of the optical fiber after the fusion splice, the fusion splice refers to the junction of the two segments of the optical fiber after the fusion splice, and the reverse stripping port position refers to the position symmetrical to the forward stripping port in the fiber laser. Figure 4 , Figure 4 is a schematic diagram of the target positions in forward transmission of an embodiment of the cladding light stripping method of the present application. As shown in Figure 4 , when the transmission direction is forward transmission, the target positions are in turn: the stripping port position, the first segment of the fusion splice optical fiber, the first optical fiber fusion splice, the second segment of the fusion splice optical fiber, the reverse stripping port position, …, the stripping port position, the (2M-1)th segment of the fusion splice optical fiber, the Mth optical fiber fusion splice, the 2Mth segment of the fusion splice optical fiber, and the reverse stripping port position, M is a natural number.

[0081] In a specific implementation, when the transmission direction is reverse transmission, the target positions are in turn: a reverse stripping port position, a 2Nth segment of fusion-spliced optical fiber, an Nth fusion-spliced optical fiber, a (2N-1)th segment of fusion-spliced optical fiber, a stripping port position, …, a reverse stripping port position, a second segment of fusion-spliced optical fiber, a first fusion-spliced optical fiber, a first segment of fusion-spliced optical fiber, and a stripping port position, where N is a natural number.

[0082] Step S203: determining the target glue required by the cladding light to be stripped at the target position according to the energy information, the divergence angle information, and the optical fiber type information.

[0083] It can be understood that the embodiment can determine the target glue required at the target position according to the energy information, the divergence angle information, and the optical fiber type information of the cladding light to be stripped at the target position, and specifically can include the type and amount of the target glue to be used to strip the cladding light to be stripped.

[0084] The embodiment obtains the optical fiber type information corresponding to the optical fiber through which the cladding light to be stripped passes, then obtains the transmission direction of the cladding light to be stripped, determines the target position according to the transmission direction, and determines the target glue required by the cladding light to be stripped at the target position according to the energy information, the divergence angle information, and the optical fiber type information. The embodiment determines the target position according to the transmission direction of the cladding light to be stripped, can obtain the target positions through which the cladding light to be stripped passes in turn in the process of transmission of the fiber laser, and determines the target glue required by the cladding light to be stripped at the target position according to the energy information, the divergence angle information, and the optical fiber type information, so as to accurately determine the target glue required by the cladding light to be stripped at the target position, thereby effectively stripping the cladding light in the subsequent process.

[0085] Reference Figure 5 , Figure 5 FIG. 3 is a flowchart of a third embodiment of the cladding light stripping method.

[0086] Based on the above embodiments, in the embodiment, the step S203 includes:

[0087] Step S2031: when the transmission direction is forward transmission, determining the target glue required by the cladding light to be stripped at the stripping port position, the target glue required by the cladding light to be stripped at the (2M-1)th segment of fusion-spliced optical fiber, the target glue required by the cladding light to be stripped at the Mth fusion-spliced optical fiber, the target glue required by the cladding light to be stripped at the 2Mth segment of fusion-spliced optical fiber, and the target glue required by the cladding light to be stripped at the reverse stripping port position according to the energy information, the divergence angle information, and the optical fiber type information.

[0088] It can be understood that when the transmission direction is forward transmission, the target glue required for the stripped cladding light at the stripping port position, the target glue required for the optical fiber at the (2M-1)th fusion joint, the target glue required for the optical fiber at the Mth fusion joint, the target glue required for the optical fiber at the 2Mth fusion joint, and the target glue required for the optical fiber at the reverse stripping port position, that is, the target glue required for the stripped cladding light at the stripping port position, the target glue required for the optical fiber at the first fusion joint, the target glue required for the optical fiber at the first fusion joint, the target glue required for the optical fiber at the (2M-1)th fusion joint, the target glue required for the optical fiber at the Mth fusion joint, the target glue required for the optical fiber at the 2Mth fusion joint, and the target glue required for the optical fiber at the reverse stripping port position can be determined in sequence according to the energy information, the divergence angle information, and the optical fiber type information.

[0090] Further, in order to determine the target glue required by the to-be-stripped cladding light at the stripping port position, in the embodiment, the step of determining the target glue required by the to-be-stripped cladding light at the stripping port position according to the energy information, the divergence angle information and the fiber type information when the transmission direction is forward transmission specifically comprises: determining first energy information, first divergence angle information and first fiber type information of the to-be-stripped cladding light at the stripping port position according to the energy information, the divergence angle information and the fiber type information when the transmission direction is forward transmission; determining the target glue required by the to-be-stripped cladding light at the stripping port position according to the first energy information, the first divergence angle information and the first fiber type information, the target glue comprising high-refractive-index glue or low-refractive-index glue, the high-refractive-index glue comprising glue with a refractive index in the range of 1.5-1.6, and the low-refractive-index glue comprising glue with a refractive index in the range of 1.3-1.4; determining second energy information, second divergence angle information and second fiber type information of the to-be-stripped cladding light at the (2M-1)th segment fusion splicing point fiber according to the energy information, the divergence angle information and the fiber type information; determining the target glue required by the to-be-stripped cladding light at the (2M-1)th segment fusion splicing point fiber according to the second energy information, the second divergence angle information and the second fiber type information, the target glue comprising high-refractive-index glue or low-refractive-index glue; determining third energy information, third divergence angle information and third fiber type information of the to-be-stripped cladding light at the 2Mth segment fusion splicing point fiber according to the energy information, the divergence angle information and the fiber type information; determining the target glue required by the to-be-stripped cladding light at the 2Mth segment fusion splicing point fiber according to the third energy information, the third divergence angle information and the third fiber type information, the target glue comprising high-refractive-index glue or low-refractive-index glue; determining fourth energy information, fourth divergence angle information and fourth fiber type information of the to-be-stripped cladding light at the reverse stripping port position according to the energy information, the divergence angle information and the fiber type information; and determining the target glue required by the to-be-stripped cladding light at the reverse stripping port position according to the fourth energy information, the fourth divergence angle information and the fourth fiber type information, the target glue comprising high-refractive-index glue or low-refractive-index glue.

[0091] It can be understood that when the transmission direction is forward transmission, the first energy information corresponding to the position of the stripping fiber port of the to-be-stripped cladding light can be selected from the energy information, the first divergence angle information corresponding to the position of the stripping fiber port of the to-be-stripped cladding light can be selected from the divergence angle information, the first fiber type information corresponding to the position of the stripping fiber port of the to-be-stripped cladding light can be selected from the fiber type information, and then the target glue required by the to-be-stripped cladding light at the stripping fiber port position is determined according to the first energy information, the first divergence angle information and the first fiber type information, and it is determined whether the to-be-stripped cladding light at the stripping fiber port position requires high refractive index glue or low refractive index glue. The high refractive index glue can be glue with a refractive index in the range of 1.5-1.6, and the low refractive index glue can be glue with a refractive index in the range of 1.3-1.4.

[0092] Further, the embodiment can also determine the target glue required by the to-be-stripped cladding light at the (2M-1) segment fusion point fiber according to the above-mentioned manner. The specific manner can be that the second energy information corresponding to the position of the stripping fiber port of the to-be-stripped cladding light is selected from the energy information, the second divergence angle information corresponding to the position of the stripping fiber port of the to-be-stripped cladding light is selected from the divergence angle information, and the second fiber type information corresponding to the position of the stripping fiber port of the to-be-stripped cladding light is selected from the fiber type information. Then, the target glue required by the to-be-stripped cladding light at the (2M-1) segment fusion point fiber is determined according to the second energy information, the second divergence angle information and the second fiber type information, and it is determined whether the to-be-stripped cladding light at the (2M-1) segment fusion point fiber requires high refractive index glue or low refractive index glue. The target glue required by the to-be-stripped cladding light at the 2M segment fusion point fiber can also be determined according to the third energy information, the third divergence angle information and the third fiber type information, and it is determined whether the to-be-stripped cladding light at the 2M segment fusion point fiber requires high refractive index glue or low refractive index glue. The target glue required by the to-be-stripped cladding light at the reverse stripping fiber port position can also be determined according to the fourth energy information, the fourth divergence angle information and the fourth fiber type information, and it is determined whether the to-be-stripped cladding light at the reverse stripping fiber port position requires high refractive index glue or low refractive index glue.

[0093] It should be understood that when the transmission direction is reverse transmission, the target glue required by the to-be-stripped cladding light at the stripping fiber port position can also be determined according to the above-mentioned manner.

[0094] In a specific implementation, when the transmission direction is forward transmission or reverse transmission, the embodiment can also determine the target glue required by the to-be-stripped cladding light at the second M segment fusion splice point optical fiber according to the energy information, the divergence angle information and the optical fiber type information, the target glue including high refractive index glue or low refractive index glue, the inner cladding having a certain energy of the cladding light, when the to-be-stripped cladding light passes through the second M segment fusion splice point optical fiber, the high refractive index glue can be selected to guide the to-be-stripped cladding light out, or the low refractive index glue can be selected to confine the to-be-stripped cladding light, and whether the to-be-stripped cladding light is guided out or confined needs to be determined according to the type of the target glue. Moreover, if the high refractive index glue is used to guide the to-be-stripped cladding light out, the amount of the high refractive index glue needs to be determined according to the energy information of the to-be-stripped cladding light, and the greater the energy, the more the amount of the high refractive index glue required.

[0100] It should be understood that when the transmission direction is forward transmission, the embodiment can first perform primary stripping of the to-be-stripped cladding light by the target glue corresponding to the stripping port position, after the primary stripping, perform low-refractive-index glue binding or high-refractive-index glue leading-out of the to-be-stripped cladding light after the primary stripping by the target glue corresponding to the (2M-1)th fusion joint optical fiber, the embodiment can perform step-by-step leading-out according to the size of the cladding light energy to avoid heat accumulation, then perform stripping of the to-be-stripped cladding light after the processing by the target glue corresponding to the Mth fiber fusion joint, then perform low-refractive-index glue binding or high-refractive-index glue leading-out of the to-be-stripped cladding light after the processing by the target glue corresponding to the 2Mth fusion joint optical fiber, and so on, and finally perform stripping of the remaining cladding light after the processing by the target glue corresponding to the reverse stripping port position.

[0101] In a specific implementation, when the transmission direction is reverse transmission, the embodiment can first perform primary stripping on the to-be-stripped cladding light through the target glue corresponding to the reverse stripping port position, then perform low-refractive-index glue binding or high-refractive-index glue leading out on the to-be-stripped cladding light after the primary stripping through the target glue corresponding to the 2Nth segment of the fusion splicing point of the optical fiber, then perform stripping on the to-be-stripped cladding light after the processing through the target glue corresponding to the Nth optical fiber fusion splicing point, then perform low-refractive-index glue binding or high-refractive-index glue leading out on the to-be-stripped cladding light after the processing through the target glue corresponding to the (2N-1)th segment of the fusion splicing point of the optical fiber, and so on, and finally perform stripping on the to-be-stripped cladding light after the processing through the target glue corresponding to the stripping port position.

In the embodiment, when the transmission direction is forward transmission, the target glue required by the to-be-stripped cladding light at the stripping port position, the target glue required by the to-be-stripped cladding light at the (2M-1)th segment of the fusion splicing point of the optical fiber, the target glue required by the to-be-stripped cladding light at the Mth optical fiber fusion splicing point, the target glue required by the to-be-stripped cladding light at the 2Mth segment of the fusion splicing point of the optical fiber, and the target glue required by the to-be-stripped cladding light at the reverse stripping port position can be sequentially determined, so that the cladding light can be effectively stripped through the target glue corresponding to each target position.
