Abstract
A semiconductor-laser-pumped solid-state laser apparatus having a semiconductor laser device, a solid state laser medium, and laser resonators. The semiconductor laser device has a plurality of emission points which are arranged on a straight line and from which pump light is generated. The laser resonators are disposed in correspondence with the emission points. A plurality of solid state laser beams can be generated by using one solid state laser medium.
Claims11
A semiconductor-laser-pumped solid-state laser apparatus comprising:
- a semiconductor laser device for generating pump light;
- a solid state thin plate laser medium pumped by the pump light disposed adjacent to said semiconductor laser device, said laser medium efficiently confining the pump light therein by repeated reflection of the pump light on both an upper and lower surface of said laser medium;
- and
- laser resonator means having a pair of reflecting surfaces facing each other with said solid state laser medium interposed therebetween, said laser resonator means being for emitting a plurality of laser light beams;
- wherein said semiconductor laser device has a plurality of emission points which are arranged on a straight line and from which the pump light is generated, and said laser resonator means is disposed in correspondence with the emission points such that said plurality of laser light beams are emitted.
A semiconductor-laser-pumped solid-state laser apparatus comprising:
- a semiconductor laser device for generating pump light;
- a solid state thin plate laser medium in which the pump light is confined by internal reflection and which is pumped by the pump light;
- and
- laser resonator means having a pair of reflecting surfaces facing each other with said solid state laser medium interposed therebetween, said laser resonator means being for emitting a plurality of beams of laser at a laser beam emitting said thereof;
- said laser resonator means further having at least one microlens disposed in an output path of a respective one of said plurality of beams of laser light.
