Master oscillator, laser system, and laser light generation method

摘要

A master oscillator may include: 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; at least one optical shutter disposed in the optical path between the seed laser and the amplifier; and a controller that causes the pumping laser to oscillate continuously at a predetermined repetition rate and that controls the optical shutter to open and close.
