Abstract

PURPOSE:To obtain a high output slab type solid state laser device having less optical distortion by cooling a whole laser medium with the same flowing refrigerant. CONSTITUTION:In a laser having a laser medium 1 of substantially rectangular section including two optically smooth surfaces, in which a laser beam 7 is reciprocated while the beam is internally totally reflected plural times on the smooth surfaces, the whole laser medium 1 is cooled by the same flowing liquid refrigerant 9. For example, a window 20 is composed of a base material having the same refractive index as that of the laser medium, and the beam 7 is incident to the medium 1 and the window 20 at a Brewster angle theta determined by the refractive indices n2 and n2 of the refrigerant 9 and the medium 1 so that the longitudinal end face 1a of the medium is disposed in parallel with the window 20. Thus, since the medium 1 is cooled on the whole periphery uniformly by the refrigerant 9, temperature difference in the medium is minimized, and a high output laser radiation having less optical distortion is obtained.
