Abstract:
A semiconductor laser excitation solid-state laser device characterized by comprising:a partial reflector that partially transmits a laser beam and a total reflector that totally reflects said laser beam, which are disposed opposite to each other through a laser medium along a longitudinal direction of said laser medium,a semiconductor laser package that excites the laser medium, anda passage that guides an excitation light which is transmitted from a main body of said semiconductor laser package to the laser medium,wherein as said passage that guides the excitation light, the structure of a total reflective light guide duct is applied,a light outgoing section of said semiconductor laser package is inserted into said total reflective light guide duct, anda gap between a semiconductor laser bar which forms the light outgoing section of said semiconductor laser package and said total reflective light guide duct is sealed with an airtight seal material.
