Nd: YAG Q-Switched Pulse Laser
The Dawa series lasers, developed in 2007, feature an industrial-grade design compatible with OEM system integration. These lasers are suitable for a variety of applications including LIBS, LIDAR, laser-induced fluorescence, laser ultrasound, and LCD repair. The Dawa series cover 1-20Hz with pulse energy ranging from 100 mJ to 300 mJ@1064nm. It also offers optional SHG, THG, and FHG.
With a compact and robust structure, the Dawa series is designed with a strong emphasis on safety and electromagnetic compatibility, crucial for system integration. The safety features include protective shutters, internal power interlocks, flow switches, emergency stop switches, and casing protection. The Dawa series achieved CE certification in 2014.
