Abstract: A laser system may include: a master oscillator configured to output pulsed laser light; an amplification device for amplifying the pulsed laser light from the master oscillator; a first timing detector configured to detect a first timing at which the master oscillator outputs the pulsed laser light; a second timing detector configured to detect a second timing at which the amplification device discharges; and a controller configured to, based on results of detection by the first timing detector and the second timing detector, control at least one of the first timing and the second timing so that the amplification device discharges when the pulsed laser light passes through a discharge space of the amplification device.

Abstract: A laser apparatus may include a laser oscillator capable of tuning a spectral bandwidth of a laser beam to be outputted therefrom, a spectrum detecting unit that detects a spectrum of the laser beam outputted from the laser oscillator and an attenuation unit capable of regulating light intensity of the laser beam that enters the spectrum detecting unit. The attenuation unit may include a variable attenuator whose transmittance varies depending on an incident position of the laser beam and a movement mechanism that moves the variable attenuator so that the incident position of the laser beam is changed.
