Abstract
A wavelength-conversion laser capable of maintaining a single longitudinal mode even when the temperature of a resonator changes. The wavelength-conversion laser is made up of a solid-state laser crystal doped with Neodymium which is pumped by light, a nonlinear optical crystal disposed in a resonator for converting the wavelength of a solid-state laser bee emanated from the solid-state laser crystal, and an etalon disposed in the resonator for realizing a single longitudinal mode. The nonlinear optical crystal is a crystal, which effects type-I phase-matching, such as MgO:LiNbO.sub.3 crystal. Moreover, the nonlinear optical crystal possesses periodic domain reversals.
