The 457nm lasers are the dominant products of new industrial lasers all the time, which use semiconductor pumped frequency doubling technology. The color of 457nm blue laser is fuller than that of 473nm blue light, and the short pulse with high repetition rate and high power can be obtained by acousto-optic Q-switching. The study of underwater blue light transmission is an important part of the underwater blue ray fuze communication technology and fuze target detection technology. It has significance meaning to build an underwater intelligent weapon communication system.
The main components of device are:
TEC1 and TEC2——TEC1 and TEC2 perform double-channel refrigeration on LD and Nd:YVO4, and refrigerating by fine-tuning semiconductor refrigerators to preventing laser threshold from rising. The precision of temperature control is 0.02 ℃.
