A DPM crystal is include at no extra cost when you purchase any 808nm laser diode module

Most applications of these 808nm laser diode modules are for making GreenDPSS laser units. As shown in the main picture is our 808nm 200mW laser diode unit pumping a DPM laser Unit or Diode Pumped Microchip laser. Which consist of a Nd:YVO4 and a KTP crystal optically glued together. Focus the 808nm laser into the Nd:YVO4 side and out the KTP side is your Green laser light.
