PURPOSE:To prevent the thermal breakdown of a solid-state laser medium by forming both end surfaces into a Brewster angle, housing the solid-state laser media divided into the plural into a transparent vessel and filling the vessel with matching oil having the same refractive index as the solid-state laser media. CONSTITUTION:A vessel 1 is constituted by a case in which both end surfaces 2, 2' formed at a Brewster angle and oppositely faced upper and lower both surfaces 3, 3' mutually running parallel are made transparent. Antireflection multilayer films are attached at both ends 2, 2'. A laser medium 4 is supported into the vessel 1 by the lower surface 3' of the vessel, and divided into the plural in parallel regarding the direction of course of beams. The laser medium 4 and the space of the vessel 1 are filled with matching oil 6 having the same refractive index as the laser medium 4, and the matching oil passes through a large number of inflow ports 7 and outflow ports 8 shaped on both sides of the vessel 1 to cool the laser medium. Lamp houses 9, 9' are fitted, and flash lamps 10, 10' are installed into the lamp houses. The lamps 10, 10' are cooled by a coolant passing through inflow ports 11, 11' and outflow ports 12, 12'. |
