Claims

[Claims for Utility Model Registration] (1) A plate-shaped slab-type laser medium that is movably arranged with respect to a base and has a width wider than the width of the excitation light irradiation area, with cooling surfaces facing each other. The laser medium is reciprocated between the cooling plates by a driving means, and a part of the laser medium is irradiated with the excitation light. In a solid-state laser device that performs laser oscillation while changing the irradiation position, a cooling plate is provided between each of the pair of cooling plates and the base side so that the cooling plates and the base side are moved toward or away from each other. A biasing means for biasing is provided, and the biasing means is disposed between the base side and the cooling plate against the biasing force of the biasing means, and the gap between the base and the laser medium is adjusted and kept constant. A solid-state laser device characterized by being provided with a gap adjusting means for holding. (2) In the fixed laser device according to claim (1),
The solid-state laser device is characterized in that the gap adjusting means is attached to a cooling plate side, and the urging means urges the cooling plate toward a base to bring the gap adjusting means into contact with the base.
