Problems solved by technology

[0003] The mirror is an extremely important optical component of the array semiconductor laser, which is responsible for reflecting the light of each semiconductor laser to the same direction, and the coupling accuracy of the mirror directly affects the quality of the array semiconductor laser; the existing array semiconductor laser Most of the mirrors use manual coupling or semi-automatic coupling. Manual coupling requires the operator to power on the semiconductor laser in advance to make it emit laser light, and then use the device to set the mirror on the optical path, and make the laser irradiate to the specified angle through subtle adjustments. , after determining the coupling position, it is necessary to fix the reflector on the carrier through colloid. The whole process is cumbersome and time-consuming, and it is necessary to ensure that the reflector will not be polluted throughout the process, otherwise it will easily affect the reflection quality of the laser. , if the power of the semiconductor laser is too high, it may also affect the personal safety of the operator; among them, the clamping of the reflector in the semi-automatic coupling usually adopts a single clamping method such as clamping or air suction, and its clamping efficiency is low. The holding accuracy is not high. In order to adapt to the single clamping method, it is usually necessary to transfer the mirror from the original tray to the special tray for clamping. This step greatly increases the coupling time and reduces the coupling efficiency.
