Diode Pumped Solid State laser is solid state laser. It's made by pumping a solid gain medium with a laser diode. Diode Pumped Solid State laser is also called DPSS laser. Laser pumping is the energy transfer from an external source into the gain medium of a laser.
According to the colors, the DPSS lasers (Solid State Lasers) are classified into green DPSS laser, red DPSS laser, blue DPSS laser, infrared DPSS laser. They are used in different applications.
