Abstract
An injection locking type or MOPA type of laser device capable of always obtaining stable output energy and wavelength is provided. For this purpose, the laser device includes an oscillator ( A) for oscillating seed laser light ( A) with wavelength band-narrowed by a band-narrowing unit ( ), an amplifier ( B) for amplifying the seed laser light and emitting the amplified laser light ( B), a wavelength monitor ( A) for detecting at least a wavelength characteristic of the seed laser light, and a laser controller ( ) for performing adjustment oscillation to contain a wavelength characteristic within a predetermined allowable range, at a time of startup or when laser oscillation is suspended for a predetermined period of time or more.
