Low Power DPM Crystal
Diode-Pumped
Solid State (DPSS) lasers are the ideal laser tools of machining,
material processing, spectroscopy, wafer inspection, light
show, medical diagnostics and other applications. CASIX has
developed DPM (Diode-Pumped Microchip laser) crystals which
combine Nd:YVO4 and KTP. The DPM crystals are mainly used
for low power applications, for example, the Green Laser Pointers.
The pump power for the Low Power DPM crystals is suggested to be less than 300mW, and the generated green output power could be less than 10mW. And a heat deposit mechanics is needed.

High Power DPM Crystal
A new microchip crystal assembly (DPM) is available in CASIX for high power Diode Pumped Green Lasers. This new type of DPM, consist of Nd:YVO4 and KTP, could used for high pump power, and generated high power green laser output. The typical pump power is suggested to be less than 500mW, and the generated green output power could be about 60mW. And a heat deposit mechanics is needed.
This DPM microchip lasers could be used in some laser display systems, for example: Green Laser Module, 3D lasers, Club lasers and Disco lasers.
