75W Laser Gain Module
Laser gain module is the heart of DPSS (Diode-Pumped Solid-State) lasers or laser amplifiers. We provide DPSS laser gain modules based on CW or QCW diode pumping technology. Design flexibility allows for variety crystal materials, rod lengths, diameters, diode laser structures and operation modes to be widely used in both resonator and amplifier designs. Customized laser gain modules can be designed and provided on request.
The DPSS laser gain module provides stable 1064nm/75W laser output from 3mm diameter Nd:YAG crystal rod.
Features
ü High pump power efficiency
