Description
A heart of Diode-Pumped Solid-State (DPSS) lasers or laser amplifiers are Laser Gain Module (pump chamber). By evolving laser gain modules, Geola Digital can provide DPSS laser gain modules based on Vertical Cavity Surface Emitting Laser (VCSEL) pumping engine technology. Our DPSS laser gain module engines assures uniform gain distribution, high pumping efficiency and long life time. We have two types of gain modules, namely Water-cooled gain modules and Passively-cooled gain modules. Typical air cooled DPSS Gain modules can be applicable for Nd:YAG Master Oscillator or Nd:YAG laser amplifier. The customized gain modules can be also provided on request.
