Abstract
Disclosed is a laser device including: a laser light source configured to emit laser light; a phase control unit configured to receive the laser light emitted from the laser light source, to control a spatial phase of a portion of the laser light, to emit the portion of the light as control light, and to emit another portion of the laser light as non-control light; a first optical system configured to irradiate an object with the control light emitted from the phase control unit; a detector configured to detect the non-control light emitted from the phase control unit; a second optical system configured to cause the non-control light emitted from the phase control unit to converge toward a detection surface of the detector.
