What is a DSPP laser pointer?

A semiconductor-pumped solid-state Laser (DPSS Laser) is Pumped by the Laser to a Solid gain medium, for example, a ruby or neodymium-doped YAG Laser crystal, with a Solid State Laser made from a Laser Diode. Semiconductor-pumped solid-state lasers use semiconductor-pumped lasers at fixed wavelengths as pumping sources, replacing the krypton lamp or xenon lamp used to pump laser crystals, and they are commonly found in green and other colored green laser pointer. DPSS laser is a kind of long life, low power consumption, high stability, good beam quality, able to miniaturization and other advantages of a new generation of solid state laser and DPSS laser has been used in optical fiber communication, space communication, environmental science, atmospheric research, laser printing, medical equipment, optical image processing, and other high-tech fields [1]. This is a new type of laser with a wide range of applications and rapid international development in recent years [2]. It makes the solid state laser has the brand-new development, therefore also called "the second generation laser".
