Abstract
The present invention relates to a laser oscillation method for effectively suppressing fluctuations in pulse widths. The laser oscillation method oscillates a pulsed beam in a laser that comprises pumping means, a resonator, Q-switching means and a controller. The pumping means continuously supplies pumping light to a gain medium, which is arranged on the resonating optical path of the resonator and generates emission light by being supplied with pumping energy. The Q-switching means modulates the resonator losses of the resonator. The controller controls an extinction ratio of Q-switching means to a value that has been selected in accordance with the frequency of repeat use in the pulsed beam such that fluctuations in the full width at half maximum of a pulsed beam outputted from the laser are within a prescribed range of the region of frequency of repeat use used by the Q-switching means.
