LASER DEVICE

摘要

Provided is a laser device that may comprise: a first laser resonator that is configured so as to generate a laser beam; a first optical element that is configured so as to adjust the divergence of the laser beam in a first direction; a second optical element that is configured so as to adjust the divergence of the laser beam in a second direction that is perpendicular to the first direction; a measurement device that is configured so as to measure the divergence of the laser beam in the first direction and the second direction; and a control unit that is configured so as to control at least one of the first optical element and the second optical element on the basis of the divergence of the laser beam in the first direction and the second direction as measured by the measurement device.
