Abstract
An example of the disclosure is a laser apparatus including a master oscillator capable of outputting a pulse laser beam, a plurality of optical amplifiers disposed on an optical path of the pulse laser beam outputted from the master oscillator and configured to sequentially amplify the pulse laser beam, an optical reflector capable of passing the pulse laser beam therethrough and reflecting a self-oscillation beam generated in one of the plurality of optical amplifiers, and an optical absorber capable of receiving and absorbing the self-oscillation beam reflected by the optical reflector.
