Continuous-wave ultraviolet laser light generating apparatus
First Claim
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.

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 LUL 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 ATiOXO4 where A depicts any one of K, Cs and Rb and X depicts any one of P and As.
