Semiconductor laser pumped solid-state laser device |
摘要 |
A compact semiconductor laser pumped solid-state laser device is provided that can suppress unnecessary parasitic oscillation in a microchip and efficiently extract energy. The semiconductor laser pumped solid-state laser device comprises: a solid-state laser core 1 disposed in the center and formed of a laser medium containing neodymium (Nd) as a laser oscillation element; a light guide region 2 integrally formed around the solid-state laser core 1, having approximately rectangular shape with four linear light entrance windows formed on the outer periphery thereof, and containing samarium (Sm) as a laser oscillation element; and a heat sink 4 disposed on one face of the light guide region 2 including the solid-state core 1, wherein laser oscillation is performed by introducing a pumping light 14 through the light entrance windows 3 and propagating the pumping light 14 through the light guide region 2 to pump the solid-state laser core 1, and wherein a laser oscillation light is extracted from the upper face of the solid-state laser core 1 opposite to the face contacting the heat sink 4. |
