The RBA SilentLightTM series laser module incorporates a number of design enhancements that significantly reduce optical noise and improve beam pointing performance when operating in TEM00 laser resonators. With power ranges from 10W to 100W, the SilentLight module was designed to meet the needs of high finesse (single transverse mode, low noise) Q-switched laser applications.

This reliable and efficient gain module can be used as the engine in new DPSS laser system development and production, or to convert existing lamp-based laser designs to state-of-the-art diode pumping. The Nd:YAG laser rod is side pumped by long lifetime laser diode bars, and the module is cooled by re-circulating filtered water through a simple non DI water chiller system.
