Claim 11:
12. A control method for a passive Q switching laser including an excitation light source that emits excitation light and a resonator that is excited by the excitation light to emit oscillation light, comprising:
operating a signal source to output a drive signal for driving the excitation light source of the passive Q switching laser;
operating a modulation unit to modulate, on a basis of emission timing at which the oscillation light has been emitted from the resonator of the passive Q switching laser, the drive signal output from the signal source; and
operating a power source unit to drive, on a basis of the modulated drive signal, the excitation light source to emit the excitation light,
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 modulated drive signal 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.
