SGR Series Laser SGR-S800
High-energy Nd:YAG Q-switched pulsed lasers. The SGR series is a flashlamp-pumped high-energy nanosecond laser with fundamental-wavelength output energy of 400mJ-6J and optional harmonics. High energy and excellent beam quality suit laser shock peening, lidar, plasma excitation, PLD, tokamaks, laser-driven flyers, laser-matter interaction, and pumping of dye lasers, OPOs and ultrafast Ti:sapphire femtosecond lasers. Its distinctive super-Gaussian resonator produces a uniform super-Gaussian spot. The distinctive pump cavity from Beamtech-laser combines efficient, uniform reflection with suppression of parasitic oscillations. Chemical materials added to its reflective layer absorb unwanted UV emitted by the flashlamp. Modular, engineered construction ensures reliability and stability. The power/control cabinet has comprehensive external-trigger and communication interfaces for synchronized triggering and remote control. Safety and electromagnetic compatibility receive particular attention, with a protective shutter, power-supply interlock, flow switch, emergency stop and enclosure-opening protection.
