Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-4 As shown, a laser aging test device includes a bracket 1, a chassis 2, a drawer 3, and a testing mechanism 4. The bracket 1 is assembled from aluminum alloy beams and includes a horizontal beam 11, a vertical beam 12, and a longitudinal beam 13. The horizontal beam 11 and the longitudinal beam 13 are combined into a frame-shaped structure and mounted on the vertical beam 12, dividing the bracket 1 into multiple vertically stacked compartments. Each compartment houses a chassis 2, which has an opening on one side. The drawer 3 is inserted into the opening and connected to the chassis 2 in a push-pull manner. The drawer 3 houses multiple testing mechanisms 4 capable of performing aging tests. The bracket 1 has a simple structure and is easy to assemble. It is equipped with multiple compartments, and the drawers in each compartment can simultaneously perform aging tests on multiple lasers 8, greatly improving testing efficiency. In addition, the lasers can be removed and installed by opening the drawer 3, which is simple and easy to assemble. The aging test is performed after the drawer 3 is closed. The drawer 3 is pushed into the chassis 2, and the testing mechanism 4 is sealed, preventing damage to the operator's eyes from the light beam during the test.

[0023] like Figure 2 、 4 As shown, multiple test mechanisms 4 are installed in the drawer via a support plate 5. The support plate 5 is a U-shaped bent member, creating a receiving cavity between the support plate 5 and the drawer 3. Downward-bent edges 51 are provided on both sides of the support plate 5, which abut against the sides of the drawer 3. Furthermore, fan-shaped notches are provided at the four corners of the top flat plate of the support plate 5, which facilitate manual insertion and removal of the support plate from the drawer 3. During installation, the test mechanism 4 is first mounted on the support plate 5, and then the support plate 5 is placed in the drawer 3, with the bottom surface of the support plate 5 abutting against the bottom surface of the drawer 3. This structure is simple, easy to assemble and disassemble, and provides a stable installation.

[0024] like Figure 2 、 3As shown, the testing mechanism 4 includes an integrating sphere 41 and a temperature sensor. A photodetector is provided inside the integrating sphere 41 for testing the power of the laser 8. The integrating sphere 41 is arranged corresponding to the laser 8 and is arranged opposite to the optical fiber of the laser 41 so that the optical fiber beam of the laser 8 is incident into the integrating sphere 41. The temperature sensor (not shown in the figure) is provided on the laser 8 for detecting the temperature of the laser.

[0025] like Figure 4 As shown, the aforementioned laser aging test device further includes a circuit board 7 located on the bottom surface of the drawer 3. The circuit board 7 is electrically connected to the integrating sphere 41 and the temperature sensor, and provides power to the laser 8. During the test, the circuit board 7 powers the laser 8 to be tested. Simultaneously, the integrating sphere 41 detects the power of the laser 8, and the temperature sensor detects the temperature of the laser 8. The circuit board 7 collects temperature and optical power data to determine the fluctuations in optical power and temperature when the laser is lit for a long time. The collected optical power and temperature data are then transmitted to the host computer software for analysis and processing to obtain the test results, ensuring an accurate test structure.

[0026] Example 2

[0027] Based on the structure of Example 1, Figure 2-4 As shown, the laser aging test apparatus further includes a water-cooling plate 6, to which each laser 8 is secured via fasteners. The water-cooling plate 6 includes a water-cooling circuit connected to a water chiller via a condenser nozzle 61. Using the water-cooling plate 6 for heat dissipation enables long-term testing while ensuring test accuracy.

[0028] Among them, such as Figure 4 As shown, the water cooling plate 6 is fixed to the top flat plate of the support plate 5 by fasteners, and the condensing nozzle 61 is installed under the water cooling plate 6 and hidden in the accommodating cavity between the support plate and the bottom of the drawer. The water pipe connecting the condensing nozzle 61 passes through the side wall of the drawer 3 and the chassis 2 in the opposite direction from the opening of the drawer 3 and is connected to the water cooler.

[0029] In addition, if Figure 2-4 As shown, integrating sphere 41 is secured to the top plate of support plate 5 via mounting bracket 42, which is adjustably connected to the top plate. Specifically, mounting bracket 42 is provided with elongated holes on either side, and the top plate of support plate 5 is provided with multiple, evenly spaced mounting holes 52 that mate with the elongated holes. The optical fibers of each laser 8 vary in length, and by adjusting the mounting position of integrating sphere 41, it can be adapted to different optical fiber lengths, providing excellent flexibility.
