solid state lasers represent a category of laser devices where the gain medium is a solid material rather than a liquid or gas. these lasers utilize a crystal or glass medium that is doped with ions that serve as the active lasing species. the most common solid state lasers use neodymium doped yttrium aluminum garnet, commonly known as nd:yag, which emits infrared light at a wavelength of 1064 nanometers.

solid state lasers are distinguished by their high power output, efficiency, and beam quality. they operate by being optically pumped, typically using flash lamps or laser diodes, which excites the ions in the gain medium to a higher energy state. when these ions return to their ground state, they release photons through stimulated emission, producing the coherent light characteristic of lasers.

these lasers find applications across numerous fields including industrial cutting and welding, medical procedures, scientific research, and military technology. their compact size, reliability, and ability to produce high peak power make them particularly valuable in environments where space or power constraints exist. modern solid state lasers continue to evolve with advances in diode pumping techniques and new gain media, expanding their capabilities and applications.
