Abstract : Solid laser Q-switching devices pumped with a semiconductor lasers (DPL) have seen rapidly development internationally in recent years. Such devices have potential advantages in multiple applications of laser radar, laser ranging, and optoelectronic countermeasures. The speed of acousto-optical Q-switching is not as high as that of electro-optical switching. However, the acousto-optical modulator has lower cavity-insertion wear, so that such modulators are suitable for solid laser devices pumped with a semiconductor laser. Internationally, the average power of a DPL acousto-optical Q-switching output is 1.6W (20nm, 160 microjoules, 10khz), the pulse upper power is 50kW (4MJ, 8ns; when its double frequency is used to pump a ti-gem laser, a continuously tunable and stable laser output is obtained in the range between 696 and 1000nm.
