Diode-pumped solid-state lasers (DPSS) are solid-state lasers made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode. DPSS lasers are known for their high power density, excellent beam quality, and high efficiency. They are commonly used in industrial settings for laser cutting, welding, and trimming. Additionally, they also find uses in military and aerospace settings. One interesting example is the AN/AQS-20A Mine Hunting System, which utilizes DPSS lasers as a means to detect and classify mines from the sea floor to the surface.
