Optical fiber laser beam shaping module

Abstract

This utility model relates to the field of fiber optic technology, specifically to a fiber laser beam shaping module, including a shaping module body and a connecting mechanism. The connecting mechanism includes a moving component, a mounting cylinder, two rotating shafts, two fixed plates, and two limiting torsion springs. The shaping module body provides the installation conditions for the connecting mechanism. When it is necessary to fix the connection between the fiber and the shaping module body, the moving component drives the mounting cylinder forward to a preset position, and then the two fixed plates are released. The rebound force of the two limiting torsion springs pushes the fixed plates to rotate on the two rotating shafts until the two fixed plates are reset, thus clamping and limiting the light at the connection point. This prevents the light from falling off due to external forces, thereby solving the problem that the fiber connection point of a fiber laser is easily detached by external forces in the application.

Description

Technical Field

[0001] This utility model relates to the field of optical fiber technology, and in particular to an optical fiber laser beam shaping module. Background Technology

[0002] Fiber lasers are lasers that use rare-earth-doped glass fibers as the gain medium. Under the action of pump light, population inversion of laser energy levels easily occurs inside the gain medium fiber. When a resonant cavity is formed, laser oscillation can be generated, thereby outputting high-power-density laser light.

[0003] Fiber lasers possess advantages such as excellent beam quality, high electro-optic efficiency, compact structure, and high reliability. Typically, the beam emitted directly from a fiber laser is a Gaussian beam with uneven energy distribution, characterized by high energy density at the center and low energy density at the edges. However, in fields such as fiber laser processing and fiber laser coherent combining, it is necessary to shape this beam into a flat-top beam to improve its energy distribution.

[0004] Currently, there are some highly integrated solutions that use two matching aspherical mirrors on the same optical material to shape fiber lasers. However, in practical applications, the fiber connection is easily affected by external forces, which can cause it to detach from the fiber. Utility Model Content

[0005] The purpose of this invention is to provide a fiber laser beam shaping module, which aims to solve the problem that fiber optic connections are easily detached by external forces in the application of fiber lasers.

[0006] To achieve the above objectives, this utility model provides a fiber laser beam shaping module, including a shaping module body and a connecting mechanism. The connecting mechanism includes a moving component, a mounting cylinder, two rotating shafts, two fixing plates, and two limiting torsion springs. The moving component is mounted on the shaping module body, the mounting cylinder is mounted on the moving component, both rotating shafts are mounted on the mounting cylinder, the two fixing plates are fixedly connected to the two rotating shafts respectively and are located on the two rotating shafts, and the two limiting torsion springs are respectively installed between the mounting cylinder and the two fixing plates.

[0007] The moving component includes a linear slide rail and a moving block. The linear slide rail is fixedly connected to the shaping module body and is located on the shaping module body. The moving block is slidably connected to the linear slide rail and is located on the moving block.

[0008] The movable component further includes a movable rod, a fixed block, and a return spring. The movable rod is slidably connected to the movable block and passes through the movable block. The fixed block is fixedly connected to the movable rod and slidably connected to the movable block, and passes through the movable block. The return spring is fixedly connected to the fixed block and is located between the movable block and the fixed block.

[0009] The mounting cylinder includes a cylinder body and two mounting brackets. The cylinder body is fixedly connected to the movable block and located on one side of the movable block. The two mounting brackets are respectively fixedly connected to the cylinder body, respectively rotatably connected to the two rotating shafts, and connected to the two limiting torsion springs.

[0010] The fixing plate includes a connecting plate, a limiting plate, and a pressing head. The connecting plate is fixedly connected to the rotating shaft and is located on the rotating shaft. The limiting plate is fixedly connected to the connecting plate and is located on one side of the connecting plate. The pressing head is fixedly connected to the connecting plate and is located on the side of the connecting plate away from the limiting plate.

[0011] This utility model discloses a fiber laser beam shaping module. The shaping module body provides installation conditions for the connection mechanism. When it is necessary to fix the connection between the fiber and the shaping module body, the moving component drives the mounting cylinder forward to a preset position, then the two fixing plates are released. The rebound force of the two limiting torsion springs pushes the fixing plates to rotate on the two rotating shafts until the two fixing plates are reset and clamp and limit the light at the connection, thus preventing the light from falling off due to external force. This solves the problem that the fiber connection is easily detached by external force in the application of fiber lasers. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-4 This utility model provides a fiber laser beam shaping module, including a shaping module body 1 and a connecting mechanism. The connecting mechanism includes a moving component, a mounting cylinder, two rotating shafts 2, two fixing plates, and two limiting torsion springs 3. The moving component is mounted on the shaping module body 1, the mounting cylinder is mounted on the moving component, the two rotating shafts 2 are both mounted on the mounting cylinder, the two fixing plates are respectively fixedly connected to the two rotating shafts 2 and are respectively located on the two rotating shafts 2, and the two limiting torsion springs 3 are respectively installed between the mounting cylinder and the two fixing plates.

[0020] In this embodiment, the shaping module body 1 provides installation conditions for the connection mechanism. When it is necessary to fix the connection between the optical fiber and the shaping module body 1, the moving component drives the mounting cylinder forward to a preset position, then the two fixing plates are released. The rebound force of the two limiting torsion springs 3 pushes the fixing plates to rotate on the two rotating shafts 2 until the two fixing plates are reset and the light at the connection is clamped and limited, thus preventing the light from falling off due to external force. This solves the problem that the optical fiber connection is easily detached by external force in the application of fiber lasers.

[0021] Furthermore, the moving component includes a linear slide rail 4 and a moving block 5. The linear slide rail 4 is fixedly connected to the shaping module body 1 and is located on the shaping module body 1. The moving block 5 is slidably connected to the linear slide rail 4 and is located on the moving block 5.

[0022] In this embodiment, the linear slide rail 4 provides the installation conditions for the moving block 5, and pushing the moving block 5 can drive the mounting cylinder to move.

[0023] Furthermore, the moving component also includes a moving rod 6, a fixed block 7, and a return spring 8. The moving rod 6 is slidably connected to the moving block 5 and passes through the moving block 5. The fixed block 7 is fixedly connected to the moving rod 6 and slidably connected to the moving block 5, and passes through the moving block 5. The return spring 8 is fixedly connected to the fixed block 7 and fixedly connected to the moving block 5, and is located between the moving block 5 and the fixed block 7.

[0024] In this embodiment, the linear slide rail 4 has multiple fixing holes 14. Pulling the moving rod 6 can drive the fixing block 7 to move away from the fixing holes 14 on the linear slide rail 4, thereby releasing the limitation on the moving block 5. The fixing block 7, in conjunction with the corresponding fixing holes 14, can limit the moving block 5. The restoring force of the return spring 8 can reset the fixing block 7.

[0025] Furthermore, the mounting cylinder includes a cylinder body 9 and two mounting brackets 10. The cylinder body 9 is fixedly connected to the movable block 5 and is located on one side of the movable block 5. The two mounting brackets 10 are respectively fixedly connected to the cylinder body 9, respectively rotatably connected to the two rotating shafts 2, and connected to the two limiting torsion springs 3.

[0026] In this embodiment, the cylinder 9 provides installation conditions for the two mounting brackets 10, and the two mounting brackets 10 provide installation conditions for the two rotating shafts 2 and the two limiting torsion springs 3.

[0027] Furthermore, the fixing plate includes a connecting plate 11, a limiting plate 12, and a pressing head 13. The connecting plate 11 is fixedly connected to the rotating shaft 2 and is located on the rotating shaft 2. The limiting plate 12 is fixedly connected to the connecting plate 11 and is located on one side of the connecting plate 11. The pressing head 13 is fixedly connected to the connecting plate 11 and is located on the side of the connecting plate 11 away from the limiting plate 12.

[0028] In this embodiment, pressing the pressing head 13 towards the side near the mounting bracket 10 can cause the connecting plate 11 to rotate on the rotating shaft 2. The rotation of the connecting plate 11 can cause the limiting plate 12 to move away from the optical fiber. Releasing the pressing head 13 can push the connecting plate 11 to reset through the rebound force of the limiting torsion spring 3, thereby causing the limiting plate 12 to reset.
