1. A continuous-wave ultraviolet laser light generating apparatus comprising:

  • a laser light source unit for generating laser light from visible light to near-infrared light;

    a wavelength converting means which comprises an optical resonator and a wavelength convertor disposed in said optical resonator for converting a wavelength of incident laser light, and converts the laser light from said laser light source unit into continuous-wave ultraviolet laser light to emit the latter;

    a locking means for adjusting said optical resonator so as to have a predetermined cavity length; and

    an electrooptic phase modulator for modulating a phase of the laser light from said laser light source unit in response to a resonance frequency of said optical resonator, wherein said electrooptic phase modulator is made of an electrooptic crystal having a composition of ATiOXO4 where A depicts any one of K, Cs and Rb and X depicts any one of P and As.
