ABSTRACT:
A resonator length can reliably be set in its locked state in the laser light generating apparatus having the resonator. The laser light generating apparatus has a nonlinear optical crystal device disposed in the resonator, at least one of reflection devices composing the resonator can be moved by an actuator to lock the resonator length with the frequency of the fundamental wave laser light. A sample-held resonator length error signal and a resonator reflected light intensity signal are used as the setting signal when the resonator length is locked by the frequency of the fundamental wave laser light.
