A laser system may include a master oscillator that outputs pulsed laser light, an amplification device that amplifies the pulsed laser light outputted from the master oscillator, and a controller that controls the master oscillator and the amplification device. The master oscillator may have a pumping laser that outputs pumping light, a seed laser that is oscillated by the pumping light, an amplifier that amplifies the pulsed laser light outputted by the seed laser using the pumping light, and at least one optical shutter disposed in the optical path between the seed laser and the amplifier. The controller may control the opening and closing of the optical shutter and discharging of the amplification device so that the amplification device discharges when the pulsed laser light that has passed through the optical shutter passes through the amplification device. |
