Product Name: REA-Series Diode-Pumped Nd:YAG Laser Modules (140W-650W)
The REA Series Laser Module delivers the reliability and performance of diode pumping to high power industrial and scientific laser systems, virtually eliminating the downtime experienced by older lamp-based laser technologies. Drive your laser system up to 650 watts of CW power @ 1064nm.
This reliable and efficient gain module can be used as the "engine" in new laser system development and production, or to convert your existing lamp-based designs to state-of-the-art diode pumping. The Nd:YAG laser rod is pumped by radial arrays of efficiently coupled long lifetime laser diode bars, and delivers good pump uniformity and stable lensing performance. The laser module requires between 60 - 120 VDC diode bias from a reliable solid-state driver, and is cooled by re-circulating filtered water from a simple chiller system.
