MASTER OSCILLATOR, LASER SYSTEM, AND LASER GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a stable laser light.;SOLUTION: A master oscillator may comprise: a pumping laser which outputs an excitation light; a seed laser which performs laser oscillation by the excitation light; an amplifier which amplifies a pulse laser light outputted from the seed laser by the excitation light; at least one optical shutter installed on an optical path between the seed laser and the amplifier; and a controller which controls opening/closing the optical shutter while oscillating the pumping laser continuously at a predetermined repetition frequency.;COPYRIGHT: (C)2013,JPO&INPIT
