Description
Technical Field
The present invention relates to an optical fiber support module for supporting an optical fiber and an optical fiber support module assembly including a plurality of optical fiber support modules, and more particularly, to an optical fiber support module through which cooling water for cooling an optical fiber can pass and an optical fiber support module assembly assembled by a plurality of optical fiber support modules.
Background
Fiber laser systems due to the waveguide structure, can be built using an active laser medium much longer than a solid-state laser. Thus, the fiber laser system has superior characteristics in terms of heat dissipation problems that may occur when oscillating a high-power laser. Therefore, the use of fiber lasers, particularly high-power fiber lasers having a double-clad structure fiber therein, is rapidly replacing the original solid-state lasers in various fields.
A general fiber laser system is constructed by delivering pump diode laser to a rare-earth doped active fiber using a lens or a fiber splicing system, thereby forming a longitudinal pumping or a transverse pumping structure. In the process of laser pumping, the rare-earth doped active fiber may generate heat because the pump light is not absorbed by the signal light.
To prevent the heating phenomenon caused by the optical fiber, cooling water may be passed through the optical fiber supporting means. When the cooling water passes through the optical fiber supporting device, a cooling system for passing the cooling water needs to be configured. If the cooling system is provided to the optical fiber supporting apparatus, the optical system for laser light and the cooling system may be disturbed, and the overall profile of the apparatus may be increased.

The fiber supporting unit 1100 may include a fiber supporting groove 1120 capable of supporting the optical fiber G. The optical fiber support groove 1120 according to an example may be provided in a holding groove shape capable of receiving the optical fiber G.

As an example, the optical fiber support groove 1120 may be formed integrally with the optical fiber support unit 1100 or be equipped and coupled to the optical fiber support unit 1100 as a separate component. In order to fix the optical fiber G placed in the fiber supporting groove 1120 to the fiber supporting unit 1100, an adhesive member capable of fixing the optical fiber G may be disposed at the fiber supporting unit 1100.
The adhesive unit 1130 is disposed between the optical fiber G and the fiber supporting unit 1100 to fix the optical fiber G to the fiber supporting unit 1100. The bonding unit 1130 according to an example may place the optical fiber G in the fiber support groove 1120 through a cooling process after melting. For example, when the adhesive unit 1130 includes a Tin-Silver (Tin-Silver) material, the optical fiber G may be fixed to the fiber support groove 1120 by applying heat to the adhesive unit 1130 after the optical fiber G is placed in the fiber support groove 1120 to melt and cool it. In the above-described embodiment, a Tin-Silver (Tin-Silver) material is illustrated as a material that may be included in the adhesive unit 1130, but may include other materials having high thermal conductivity.
The main body 1200 is a base member inserted and supported by the optical fiber support unit 1100, and includes a first flow path 1600 through which the first cooling water C1 passes and a second flow path 1700 through which the second cooling water passes.

The second channel accommodating unit 1220 may have a shape corresponding to the second channel 1700. As an example, the second flow path housing unit 1220 may include a 2-1 th flow path housing unit 1221 and a 2-2 nd flow path housing unit 1222, wherein the 2-1 st flow path housing unit 1221 extends in a second direction parallel to a plane (XY plane), and the 2-2 nd flow path housing unit 1222 is connected to both ends of the 2-1 st flow path housing unit 1221 and extends in a first direction (Z direction) perpendicular to a plane (XY plane). In the above-described embodiment, the first flow path accommodating unit 1210 and the second flow path accommodating unit 1220 are illustrated as having shapes corresponding to the first flow path 1600 and the second flow path 1700, but the first flow path accommodating unit 1210 and the second flow path accommodating unit 1220 may be provided with any shapes capable of accommodating the first flow path 1600 and the second flow path 1700.
Referring back to fig. 2 and 3, the optical fiber accommodation unit 1230 is an accommodation unit that is disposed between the first flow path accommodation unit 1210 and the second flow path accommodation unit 1220, so as to be inserted and fixed by the optical fiber support unit 1100. As an example, the optical fiber accommodation unit 1230 is a space spaced in the first direction (Z direction) between the 1 st-1 st and 2 nd-1 st flow path accommodation units 1211 and 1221. Therefore, along the first direction (Z direction), the first flow path 1600 may be disposed above and the second flow path 1700 may be disposed below the optical fiber G inserted into the optical fiber accommodation unit 1230.

The first piping unit 1300 according to an example may be disposed between the first flow passage 1600 and the cooling system (not shown), and may transfer the first cooling water C1 between the first flow passage 1600 and the cooling system (not shown). The cooling system (not shown) may include a cooling water containing unit that contains the first cooling water C1 and the second cooling water C2, and an arbitrary cooling unit that can cool the heated first cooling water C1 and the second cooling water C2.
The first pipe unit 1300 according to an example may include a 1 st-1 pipe 1310, a 1 st-2 pipe 1320, a 1 st-1 pipe fastening unit 1330, and a 1 st-2 pipe fastening unit 1340. The 1 st-1 st pipe 1310 according to an example is disposed between the first flow path 1600 and a cooling system (not shown). Thereby, the first cooling water C1 discharged from the cooling system (not shown) can flow into the first flow passage 1600. As an example, the 1 st-1 st piping 1310 may be provided in a pipe shape extending along the first direction (Z direction). At this time, the 1 st-1 st piping 1310 may be connected to the lower surface of the main body 1200. As an example, the 1 st-1 pipe fastening unit 1330 may fasten one end portion of the 1 st-1 pipe 1310 and one end portion of the first flow path 1600 to each other. At this time, the 1 st-1 pipe fastening unit 1330 may include a sealing member capable of preventing the first cooling water C1 from leaking.
The 1 st-2 nd piping 1320 according to an example is disposed between the first flow path 1600 and a cooling system (not shown). Thereby, the first cooling water C1 discharged from the first flow path 1600 can flow into the cooling system (not shown). As an example, the 1 st-2 nd piping 1320 may be provided in a pipe shape extending along the first direction (Z direction). At this time, 1 st-2 nd piping 1320 may be connected to the lower surface of the main body 1200. As an example, the 1 st-2 pipe fastening unit 1340 may fasten one end portion of the 1 st-2 pipe 1320 and one end portion of the first flow path 1600 to each other. At this time, the 1 st-2 th pipe fastening unit 1340 may include a sealing member capable of preventing the first cooling water C1 from leaking.
The second piping unit 1400 is a flow passage through which the second cooling water C2 can pass. The second piping unit 1400 according to an example may be disposed between the second flow path 1700 and the cooling system (not shown), and may transfer the second cooling water C2 between the second flow path 1700 and the cooling system (not shown). Second pipe unit 1400 according to an example can include 2-1 pipe 1410, 2-2 pipe 1420, 2-1 pipe fastening unit 1430, and 2-2 pipe fastening unit 1440. The contents of the 2-1 st pipe 1410, the 2-2 nd pipe 1420, the 2-1 st pipe fastening unit 1430, and the 2-2 nd pipe fastening unit 1440 are substantially the same as those of the 1-1 st pipe 1310, the 1-2 nd pipe 1320, the 1-1 st pipe fastening unit 1330, and the 1-2 th pipe fastening unit 1340 of the first pipe unit 1300, and thus, the description thereof will be omitted for convenience of description.
Referring back to fig. 4 and 5, the first and second flow paths 1600 and 1700 are included in the main body 1200 so that the first and second cooling water C1 and C2 can pass through. The first channel 1600 according to an example may include a 1 st-1 channel 1610 and a 1 st-2 channel 1620, wherein the 1 st-1 channel 1610 is parallel to a plane (XY plane) and has a half transverse n-shape, and the 1 st-2 channel 1620 is connected to both ends of the 1 st-1 channel 1610 and extends along a first direction (Z direction) perpendicular to a plane.
The second flow path 1700 may include a 2 nd-1 st flow path 1710 and a 2 nd-2 nd flow path 1720, wherein the 2 nd-1 st flow path 1710 extends in a second direction (Y direction) parallel to a plane (XY plane), and the 2 nd-2 nd flow path 1720 is connected to both end portions of the 2 nd-1 st flow path 1710 and extends in a first direction (Z direction) perpendicular to the plane.
As an example, the optical fiber support unit 1100 supporting the optical fiber G is disposed between the 1 st-1 st flow path 1610 and the 2 nd-1 st flow path 1710. That is, the 1 st-1 st channel 1610 and the 2 nd-1 st channel 1710 may be disposed to face each other with the optical fiber G interposed therebetween. Therefore, along the first direction (Z direction), the first channel 1600 may be disposed above the optical fiber G, and the second channel 1700 may be disposed below.
As described above, since the first channel 1600 and the second channel 1700 are disposed with the optical fiber G interposed therebetween, the cooling performance for the optical fiber G can be improved to the maximum. At the same time, by changing the shapes of the first and second flow paths 1600 and 1700 so that the first and second piping units 1300 and 1400 are disposed at the lower end of the main body 1200, the first and second piping units 1300 and 1400 can be prevented from being disposed on a plane (XY plane) on which the optical fibers G are disposed. This prevents interference between the optical system and the cooling system with respect to the optical fiber G arranged along a single plane (XY plane). In addition, since the arrangement of the plurality of fiber support modules 100 can be freely realized on a plane (XY plane), the fiber support modules 100 and the fiber support module assembly having an improved degree of freedom in design can be realized. Next, the fiber support module assembly 200 combined by the plurality of fiber support modules 100 will be described in detail.

For example, the first to third fiber support modules 101 to 103 may be disposed adjacent along a first direction (X direction), i.e., a direction perpendicular to a second direction (Y direction) in which the optical fibers G extend. In the present disclosure, the direction of aligning the first to third fiber support modules 101 to 103 is described as the first direction (X direction), but the present disclosure is not limited thereto. The first to third fiber support modules 101 to 103 according to an example may be aligned at arbitrary positions on a plane (XY plane).

That is, the first piping units 1301 to 1303 and the second piping units 1401 to 1403 may be arranged below the base unit 210 along the first direction (Z direction). Thus, the optical system arranged along a plane (XY plane) is not disturbed by the first piping units 1301 to 1303 and the second piping units 1401 to 1403, so that the first to third fiber support modules 101 to 103 can be aligned at arbitrary positions on a plane (XY plane).
In fig. 6 and 7, the number of the plurality of fiber support modules that can be arranged on the base unit 210 is limited to 3, and the positions where the plurality of fiber support modules are arranged are limited to one row, but the number and arrangement of the fiber support modules that can be arranged on the base unit 210 are not limited thereto.
