Abstract:
1. An injection locking type or MOPA type of laser device, comprising: an oscillator having an amplification discharge circuit for exciting a laser gas by oscillator discharge said oscillator emitting oscillated seed laser light having a band-narrowed wavelength; an amplifier having a discharge circuit for amplifying said oscillated seed laser light to emit amplified laser light; a delay circuit for selling at least one of a plurality of delay times between parameters associated with a synchronization process of said oscillator and said amplifier; jitter compensation circuits provided at each of said oscillator and said amplifier, each jitter compensation circuit compensating the jitter of a total elapsed time from a reference trigger signal being a reference to a start of said oscillator discharge and amplification discharge based on a charge voltage applied to each respective discharge circuit of said oscillator and said amplifier; and drift compensation circuits for compensating said jitter compensation circuits of said oscillator and said amplifier based on changes in characteristics of each respective discharge circuit.
