Abstract:
1. A laser apparatus comprising: an amplifier including at least one of a power amplifier and a power oscillator 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 comprising a semiconductor laser configured to oscillate a single-longitudinal or multiple-longitudinal mode laser light of which wavelength is within one or more amplification lines of the amplifier; a controller configured to adjust at least one of a pulse energy, a pulse width, a wavelength, and a pulse output timing of the single-longitudinal or multiple-longitudinal mode laser light outputted from the master oscillator; and a temperature regulator configured to control a temperature of the semiconductor laser, wherein the controller controls a wavelength of the master oscillator so that a wavelength of the single-longitudinal or multiple-longitudinal mode laser light outputted from the master oscillator becomes within the one or more amplification lines.
