Patent ID: 7936797

Claim:
A laser apparatus comprising: a laser light source for generating a laser light flux; an output member for receiving and transmitting the laser light flux generated by the laser light source, and outputting a laser light flux; an optical aligning member for positioning the laser light flux generated by the laser light source to the output member; a drive for driving the optical aligning member; a drive controller for controlling the drive; an output detector for outputting a detected output representing an intensity of a laser light flux outputted from the output member; and an output controller for changing a power of the laser light flux generated by the light source, wherein when the detected output is not larger than a predetermined threshold, the output controller sets the power of the laser light flux generated by the light source at a predetermined standard output, and the drive controller controls the drive to drive the optical aligning member so as to increase the detected output, and wherein when the detected output is larger than the predetermined threshold, the drive controller is stopped to statically position the optical aligning member, and the output controller controls the power of the laser light flux generated by the light source so that the detected output reaches to a predetermined target output.
