Beamtech SGR (Super-Gaussian Resonator) series Q-switched Nd:YAG lasers combine VRM (variable reflectivity mirror) and unstable resonator design creating a cavity with large TEM00 mode volume for high efficiency of excitation and energy extraction. You can specify “flat-top-hat” with uniform energy distribution or “VRM Gaussian” profiles.
The Beamtech close-coupled diffuse pump chamber delivers uniform pumping to the laser rod for optimum lasing excitation efficiency and allows for higher stored energy by eliminating parasitic oscillations within the pump chamber. The pump chamber uses chemically inert materials to withstand high pumping energy and absorb unwanted UV and IR radiation emitted by the flashlamps. One or more amplifiers can be added to the oscillator for higher energy output. With scientific or industrial grade models available, the SGR series will fit right in your scientific research, medical or OEM industrial application.
