[0002] With the development of lasers, semiconductor lasers have been widely used in the fields of industry, military, scientific research, etc. in recent years, such as laser marking, laser ranging, laser radar, and laser communication. In the above series of application fields, especially the ranging accuracy, anti-interference and power consumption of laser marking and laser ranging, the quality of laser pulses emitted by semiconductor lasers depends on the quality of laser pulses emitted by semiconductor lasers. The laser pulses emitted by semiconductor lasers are directly modulated by the electric pulses generated by the semiconductor laser driving circuit, that is, the quality of laser pulses is determined by the pulse quality of the semiconductor laser driving circuit. When the existing handheld laser is not in use, it cannot protect the laser lens, which may cause the laser lens to be polluted and damaged by external factors such as dust and water droplets, reducing the service life of the device, and it is not easy to replace the grips of different types or functions to adapt to different working scenes and needs. The practicality of the device is greatly reduced.
