[0025] Example

[0026] An aging test device for blue fiber lasers, such as Figure 1 As shown, it includes an aging fixture component 1 and a protection component 2.

[0027] like Figure 2 As shown, the aging fixture assembly 1 includes a mounting plate 11, a water-cooling plate 12, a fiber laser 13, a fiber flange 14 and a movable flange bracket 15. The water-cooling plate 12 is arranged on the surface of the mounting plate 11. The fiber laser 13 includes a tube shell 131 and an optical fiber 132 (as shown in FIG. Figure 3As shown), the tube shell 131 is arranged on the surface of the water-cooled plate 12, the end of the optical fiber 132 is connected to the optical fiber flange 14, the optical fiber flange 14 is installed on the flange bracket 15, and a magnet block is provided between the flange bracket 15 and the surface of the mounting plate 11. The magnet block adsorbs both to achieve a movable connection between the flange bracket 15 and the surface of the mounting plate 11; the optical fiber laser 13 can be arranged in one group or multiple groups, and each tube shell 131 is adjacently arranged on the surface of the water-cooled plate 12.

[0028] The water cooling plate 12 is a strip plate with a water flow channel inside and a water inlet and outlet at both ends. The specific structure is as follows: Figure 4 As shown, the water-cooling plate 12 includes a water inlet pipe 121, a matching plate 122, a main board 123, and a water outlet pipe 124. The main board 123 has a zigzag groove on its surface, with a water inlet and outlet at each end connected to the groove. The matching plate 122 has the same shape as the groove, covering the groove and sealingly connected to the main board 123, forming the water flow channel. The water inlet pipe 121 is connected to the water inlet of the water-cooling plate 12, and the water outlet pipe 124 is connected to the water outlet of the water-cooling plate 12. The water inlet and outlet of the water-cooling plate 12 are respectively connected to the water inlet and outlet of an external water chiller to achieve continuous heat dissipation for the laser.

[0029] like Figure 5 As shown, the protective assembly includes a protective cover 21, a heat dissipation pipe 22 and a pipe clamp 23. The outer surface of the protective cover 21 is provided with a pipe clamp 23, and the heat dissipation pipe 22 is fixed to the outer surface of the protective cover 21 through the pipe clamp 23. The heat dissipation pipe 22 is provided with a water inlet and a water outlet, which are respectively connected to the water inlet and outlet of the external water cooler to achieve continuous heat dissipation of the protective cover 21. Figure 1 As shown, the protective cover 21 is installed on the surface of the mounting plate 11 to cover the optical fiber 132 , the optical fiber flange 14 and the flange bracket 15 .

[0030] In specific implementation, the mounting plate 11 is made of carbon steel with a blackened surface. The matching plate 122 and the main board 123 are both made of copper. The protective cover 21 is made of metal with a blackened surface. The heat dissipation pipe 22 is made of brass.

[0031] The working process and principle of the above-mentioned blue fiber laser aging test device are as follows:

[0032] The flange bracket 15 is magnetically adsorbed on the mounting plate 11 by the magnet block, so for lasers 13 with different optical fiber lengths, the flange bracket 15 can be moved to place the optical fiber 132 in the appropriate position. After that, the positive and negative poles of the laser 13 are respectively connected to the aging power supply, and the water inlet and outlet of the protective cover 21 and the water cooling plate 12 are connected to the water cooler. By setting the parameters of the aging power supply, the laser can be subjected to aging tests under different parameter environments. During the aging operation, the laser will continue to generate heat, which will affect the life of the laser. The water cooling plate 12 can continuously take away the heat of the laser to enable the laser to operate normally. When the laser is irradiated on the protective cover 21, the surface temperature of the protective cover 21 will continue to rise. If heat dissipation is not performed, the operator may be burned when replacing the laser or removing the protective cover. Therefore, the heat dissipation pipe 22 on the outer surface of the protective cover 21 can continuously dissipate heat to avoid burns.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
