CEO’s laser resonator and laser amplifier modules are the engine that drives not only our own DPSS laser systems, but also external customers who fabricate their own DPSS laser systems. With a variety of gain medium, rod diameter, rod length and diode bar count options, these gain modules have served as a work horse for important applications such as airborne LIDAR, laser pulse train amplification, pumping Ti:Sapphire amplifiers, laser spectroscopy, and OPCPA pumping.
