Abstract
A laser treatment apparatus comprises: an optical guiding body which guides a treatment laser beam omitted from a laser source; an irradiation optical system for irradiating the treatment beam guided by the optical guiding body; a first beam splitter placed in the irradiation optical system to split the treatment beam guided thereto; a photo-detector which detects output of one of the split treatment beams; and a depolarizer placed in an optical path between the optical guiding body and the first beam splitter to spatially disturb a polarization state of the guided treatment beam.
