Abstract
A pulsed laser device includes a laser light source, an electro-optic modulator, a laser light source driver, an electro-optic modulator driver, and a controller to control the laser light source driver and the electro-optic modulator driver. The laser light source outputs pulsed laser light pulse-modulated by the laser light source driver. The electro-optic modulator outputs pulsed laser light obtained by causing the electro-optic modulator driver to pulse-modulate the pulsed laser light from the laser light source. The control unit controls the laser light source driver and the electro-optic modulator driver such that the electro-optic modulator turns on at least while the laser light source is on and the electro-optic modulator turns on at least once while the laser light source is off, thereby increasing a duty ratio of the pulse modulation for the electro-optic modulator relative to a duty ratio of the pulse modulation for the laser light source.
