REA PowerPULSE

rea_powerpulse_laser_moduleThe REA PowerPULSETM series of DPSS gain module is ideally suited for applications that require up to 4 Joules per pulse.  The PowerPULSE module brings the reliability and performance of diode pumping to high energy industrial and scientific laser systems.  It virtually eliminates the downtime and high utility costs associated with older lamp-based laser technologies.  The REA Series laser module family supports large diameter rods, up to 10mm, and high pump diode bar counts, up to 200 bars.

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