Abstract
A solid-state laser device includes a resonator composed of a pair of mirrors, a laser rod disposed in the resonator, and a laser chamber. The resonator and the laser rod are disposed in a housing. The laser rod is inserted through a hole of the laser chamber and is supported in a state in which two end portions are exposed. An O-ring is disposed at an exposed root of at least one rod end portion exposed from the laser chamber. The solid-state laser device includes a cover member that is disposed on a rod side surface of the rod end portion between the O-ring and a rod end surface and that blocks incidence of stray light, which is generated in the housing, on the O-ring.

A solid-state laser device comprising:
- a resonator composed of a pair of mirrors;
- a laser rod disposed in the resonator;
- and
- a laser chamber that contains at least a part of the laser rod,
- wherein the resonator and the laser rod are disposed in a housing,
- wherein the laser chamber comprises a hole having a columnar shape that is shorter than a longitudinal axial length of the laser rod,
- wherein the laser rod is inserted through the hole of the laser chamber and is supported in a state in which two end portions of the laser rod are exposed from the hole,
- wherein an O-ring is disposed at an exposed root of at least one end portion of the two end portions, the exposed root being exposed from the laser chamber, and
- wherein the solid-state laser device comprises a cover member that is disposed on a side surface of the laser rod between the O-ring and an end surface of the at least one end portion of the laser rod and that blocks incidence of stray light, which is generated in the housing, on the O-ring.
