Abstract
A solid state laser includes a solid state laser crystal, a pumping source for pumping the laser crystal, a resonator, an enclosed casing which is filled with gas and in which the resonator is contained, and a temperature controller which keeps the resonator at a predetermined temperature. The ratio of the optical length of the gas layer in the resonator to the oscillation wavelength of the solid state laser is set to be not larger than 13600.
