Abstract

There are disclosed a laser treatment method and an apparatus therefor in which a laser beam is irradiated on an object to be treated. The laser beam emitted from a laser apparatus is divided into a plurality of fractional beams, and the fractional laser beams are reflected toward and irradiated on an area to be irradiated of the object being treated after being compounded such that energy density distribution on the irradiated area is made substantially uniform in at least one direction.
