[0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. Semiconductor lasers are widely used in fiber optic communications, optical discs, laser printers, laser scanners, laser pointers and other fields. Before semiconductor lasers are produced, processed and put into use, they need to be tested to ensure the quality and accuracy of semiconductor lasers. This requires the use of detection devices. Existing detection equipment cannot detect different data according to different environments when used. The detection data is single and prone to errors, which is not conducive to users' detection of semiconductor lasers.

[0003] The publication (announcement) number is CN216621692U, which discloses a detection device for semiconductor lasers, including: a fixing seat; and a support frame, which is fixedly mounted on the bottom of the fixing seat; a mounting seat, which is arranged at the top of the fixing seat and located at one end of the fixing seat, for mounting the laser to be detected; a stabilizing structure, which is fixedly connected to the mounting seat and used to stabilize the mounted laser; a detection structure, which is arranged at the top of the fixing seat and located at the other end of the fixing seat, for detecting the laser emitted by the laser; an adjustment structure, which is arranged in the middle of the fixing seat and located between the mounting seat and the detection structure.
