Abstract:
1. A semiconductor laser pumped solid-state laser device, comprising; a solid-state laser core having opposing upper and lower surfaces and a peripheral surface between the upper and lower surfaces and formed of a laser medium containing neodymium (Nd) as a laser oscillation element; a light guide region integrally formed with the solid-state laser core, surrounding the peripheral surface of the solid-state laser core, the light guide region having an approximately rectangular shape with four linear light entrance windows formed in an outer peripheral surface thereof, and containing samarium (Sm), the light guide region being transmissive to a pumping light and absorbing a parasitic oscillation light from the solid-state laser core; and a heat sink on which the light guide region and the solid-state core are mounted, wherein laser oscillation is performed by introducing the pumping light through a light entrance window and propagating the pumping light through the light guide region to pump the solid-state laser core, and wherein a laser oscillation light is extracted from the upper surface of the solid-state laser core.
