High-Energy Nd: YAG Q-Switched Pulsed Laser
SGR-Extra series lasers have been developed since 2007 as high energy nanosecond laser systems which is suitable for laser peening, pump source, film damage detection，plasma physics, etc.
SGR-Extra series lasers provide the customization service. Specifications such as wavelength, repetition rate, energy, pulse width, beam profile, SLM are all available for customization. Beamtech also developed and gained much experience on burst mode technique and vehicular applications during this process. As a result, Beamtech provides the ideal laser source solution for the customer in various applications.
For industrial applications, particularly in laser shock peening, the SGR-Extra series, with its high energy output, optical shielding design, ultra-uniform beam output, high engineering reliability, and long-term operational stability, offers high-reliability and cost-effective laser solutions.
