Abstract
A laser treatment apparatus for performing treatment on a treatment part of a skin by irradiating the part with a laser beam for treatment is disclosed. The apparatus includes a laser output device which outputs the treatment beam; a hand-piece provided with at least a part of an irradiation optical system for irradiating the treatment beam of a predetermined spot size, the hand-piece being held in contact with the skin; a detector which detects a moved position of the hand-piece on the skin; and a controller which controls an ON/OFF state of laser irradiation based on the moved position detected by the detector and information on the spot size.
