摘要： A laser beam in the ultraviolet region is generated at high power for along period. A green laser beam generated by a laser oscillator comes incident into a resonator from behind a first curved mirror, and circulates there, reflected by each mirror. By passing a barium borate crystal, it causes a secondary harmonic (a laser beam in the ultraviolet region) to be generated, which is taken out of the resonator via a second curved mirror. The beam waist of the laser beam passing the barium borate crystal is set to 46 &mgr;m, about double the conventional thickness, by adjusting the distance between the first curved mirror and a second flat mirror. As a result, the power density of the laser beam in the barium borate crystal is reduced to ¼ of the value according to the related art, and it is made possible to avoid rapid degradation of the barium borate crystal by excessive squeezing of the laser beam.
