ABSTRACT:
A continuous-wave ultraviolet laser light generating apparatus includes a laser light source unit (1) for generating laser light from visible light to near-infrared light, a wavelength converting means (4) which includes an optical resonator (2) and a wavelength convertor (3) disposed in the optical resonator (2) for converting a wavelength of incident laser light and which converts the laser light from the laser light source unit (1) into continuous-wave ultraviolet laser light L.sub.UL to emit the latter, a locking means (5) for adjusting the optical resonator (2) so as to have a predetermined cavity length, and an electrooptic phase modulator (6) for modulating a phase of the laser light from the laser light source unit in response to a resonance frequency of the optical resonator. The electrooptic phase modulator (6) is made of an electrooptic crystal (11) having a composition of ATiOXO.sub.4 where A depicts any one of K, Cs and Rb and X depicts any one of P and As.
