  • Laser apparatus and extreme ultraviolet light source apparatus
    Patent number: 8311066
    Abstract: A laser apparatus comprises an amplifier including at least one of a MOPA and a MOPO each of which amplifies a single-longitudinal or multiple-longitudinal mode laser light, an amplifiable agent of the amplifier being a molecular gas, a master oscillator constructed from a semiconductor laser being able to oscillate a single-longitudinal or multiple-longitudinal mode laser light of which wavelength is within one or more amplification lines of the amplifier; and a controller executing a wave shape control adjusting a pulse shape and/or a pulse output timing of a single-longitudinal or multiple-longitudinal mode laser light outputted from the master oscillator.
    Type: Grant
