Abstract
A laser device includes at least one amplification unit configured to amplify laser light emitted from a laser oscillator, and an amplification control unit configured to control the amplification unit. The amplification unit includes an incident-side optical adjustment unit including a wavefront adjustment unit configured to adjust a wavefront of the laser light and a first direction adjustment unit configured to adjust an optical axis thereof, an amplifier configured to amplify the laser light, an emission-side optical adjustment unit including a second direction adjustment unit configured to adjust an optical axis of the laser light, and a measurement unit configured to measure the laser light and acquire information on at least one of an optical axis, a wavefront and energy of the laser light. The amplification control unit controls the incident-side optical adjustment unit and/or the emission-side optical adjustment unit, based on a measurement result of the measurement unit.
