Title: SOLID-STATE LASER DEVICE
Abstract:
A solid-state laser device of the present invention is provided with an inner container (3), an outer container (4), a cooling medium supply section (5), and a cover section 6. The inner container (3) contains a laser medium (2A), and has an inner light transmitting section (20). An outer light transmitting section 21 of the outer container (4) is provided at an area facing the inner light transmitting section (20), and is vacuum-insulated from the inner light transmitting section (20). The cooling medium supply section (5) supplies a cooling medium such that the cooling medium is in contact with a laser medium (2A) surface excluding a light input/output surface (15A). A cover section 6 demarcates a light passing region (A1) from a cooling medium supply region A2 to be supplied with the cooling medium.
