Classification: CPC H  B | IPC B  H

Claim 12:
13. A laser processing device, comprising:
a passive Q switching laser that includes an excitation light source that emits excitation light, and a resonator that is excited by the excitation light to emit oscillation light;
a signal source that outputs a drive signal for driving the excitation light source;
a modulation unit that modulates, on a basis of emission timing at which the oscillation light has been emitted from the passive Q switching laser, the drive signal output from the signal source;
a power source unit that drives, on a basis of the drive signal modulated by the modulation unit, the excitation light source to emit the excitation light; and
an emission mechanism for emitting, toward a workpiece, the oscillation light emitted from the resonator of the passive Q switching laser,
wherein the drive signal is a pulse signal,
wherein the power source unit causes the excitation light source to emit the excitation light while the drive signal modulated by the modulation unit is at an on-level, and
wherein the modulation unit modulates a time period of the on-level of the pulse signal output from the signal source.
