Dawa Series Laser Dawa-100
Nd:YAG Q-switched pulsed laser. Developed in 2007, the Dawa series uses an industrial design for OEM integration, serving LIBS, LIDAR, laser-induced fluorescence, laser ultrasound, LCD repair and other applications. This medium-to-low-energy series provides fundamental output energies from 100 mJ to 300 mJ, with optional SHG, THG and FHG harmonics. Compact and rugged for system integration, it emphasizes safety and electromagnetic compatibility, with a protective shutter, power-supply interlock, flow switch, emergency stop and cover-opening protection. The Dawa series received CE certification in 2014.
