Abstract
A high power pulsed light generation device includes: a master clock generator that generates a master signal; an optical oscillator that generates a pulsed light synchronized with the master clock signal; an optical amplifier that amplifies the pulsed light emitted from the optical oscillator to output a high power pulsed light; a pump semiconductor laser that generates a pulsed light for pumping the optical amplifier; a driving unit that drives the pump semiconductor laser by a pulsed driving current synchronized with the master clock signal; and a control unit which controls the driving unit and controls a gain of the optical amplifier for each pulse by changing a pulse width of the pulsed drive current from driving unit so as to change the pulse width of the pumping pulsed light.
