Abstract: A laser apparatus may include: an optical amplifier configured to amplify a laser beam outputted from a master oscillator; an optical-amplifier power supply configured to supply an alternating current for optical amplification to the optical amplifier; and a laser controller. The optical-amplifier power supply may include: an alternating current generation circuit including an inverter circuit configured to change output amplitude in accordance with a duty cycle, the alternating current generation circuit being configured to generate the alternating current from an output of the inverter circuit; and a power supply control circuit configured to hold control information defining correspondence relations between command values from the laser controller and duty cycles of the inverter circuit, determine a duty cycle corresponding to a command value received from the laser controller based on the control information, and provide the determined duty cycle to the inverter circuit.
