Problems solved by technology

[0002] With the improvement of the quality of semiconductor lasers and the decline of prices, the research on solid-state high-power green lasers has developed rapidly. Because of its unique double pulse signal, pulsed lasers will soon be used in material processing, laser processing, precision measurement and precision processing, etc. In the industrial environment, but this is only in the experimental stage. There is no ready-made equipment and mature technology in the market to apply pulsed lasers to industrial measurements. At the same time, the development of lasers also shows a trend of miniaturization. Therefore, , there is a need for a miniaturized dual-pulse laser that can be used for precision measurements, but there is no such device on the market today
