ABSTRACT:
A highly repetitively pulsed laser stabilizing device which comprises a laser resonator, a feedback system for optically delaying an optical pulse emitted from the laser resonator and returning it in such a manner that it is superposed on an optical pulse in the laser resonator, and a feedback system control section that monitors one of the optical pulses of the laser resonator and feedback system, and controls the optical path length of the feedback system so that the monitored optical pulse is optimum in intensity.
