Abstract
A laser-diode-pumped solid state laser in which a solid state laser crystal is pumped by a light beam produced by a laser diode and which is not lower than 10 W in the internal power of the resonator includes a temperature control circuit which keeps the inside temperature of a resonator at a predetermined temperature and, a wavelength selector which is disposed in the resonator and selects one of a plurality of oscillation modes in the resonator, thereby making the laser oscillate in a single mode. The wavelength selector has characteristics such that the increase in temperature of the wavelength selector due to absorption of a laser beam is smaller than a value such that when the temperature of the wavelength selector changes by the value or more, the oscillation mode selected by the wavelength selector changes.
