Claim 0:
1. A laser device comprising:
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; and
a control unit configured to execute a correction process for controlling the phase control unit to correct a control state for a spatial phase of the control light in the phase control unit on the basis of a detection result for the non-control light from the detector.
