ABSTRACT:
In wavelength-conversion laser, a solid state laser crystal is pumped with light and the wavelength of a solid laser beam emitted from the solid state laser crystal is converted by a nonlinear optical crystal disposed in a resonator for realizing type-I phase matching. An etalon and a Brewster's plate which functions as a polarization control element are provided in the resonator to realize a single longitudinal mode oscillation.
