257nm Microchip Laser System of MJ Series
MJ series microchip laser is a passively Q-switched solid-state laser based on semiconductor pump. The laser pulse is pure without tail, the single pulse energy is stable and the beam quality is good. The integrated design of semiconductor pump module and laser crystal makes the compact laser head easy to install and integrate. The system supports internal and external triggering. This series of products include two wavelengths of 1030nm and 515nm. The fully sealed module inside the laser head can be used by customers for secondary development and application.
