PULSE LASER DEVICE

摘要

A pulse laser device comprises: a laser source for outputting a pulse beam; a phase modulator for changing the phase of the pulse beam output from the laser source; a beam detector for detecting a pulse beam output from the laser source and outputting a detection signal that is a time-based waveform of a change in intensity; and a phase modulator driving power source for outputting a drive signal generating a phase change in proportion to the time-based waveform of the change in intensity on the basis of the detection signal output from the beam detector, and driving the phase modulator.
