STGR
Series Super-Gaussian Resonator series Q-Switched Nd:YAG lasers combine VRM
(variable reflectivity mirror) with unstable resonator design creating a cavity
with large TEM00 mode volume for excitation and energy extraction. A
�flat-top-hat� can be specified with uniform energy distribution or �VRM
Gaussian� profiles.
STGR
Series close-coupled diffuse pump chamber delivers uniform pumping of 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 flash lamps. One or more amplifiers
can be added to the oscillator for higher energy output. With scientific or
industrial grade models available, the STGR series will
fit right in with your scientific research, medical or OEM industrial
application.
