Not only are various tools needed to be carried for fixing and measuring, but also the whole detection process is exposed, and the operator also needs to be additionally provided with goggles to prevent the glasses from being injured; thirdly, data repeatability is poor because the relative position of the laser arm and the probe is not easy to fix.

Therefore, it is highly desirable to develop a portable laser power detection auxiliary device, which can quickly assemble and adjust the relative position between the laser light guide arm and the external laser power probe of the laser detection device, ensure that laser can be irradiated into the measurement area of the laser power meter, and realize laser power detection.
