Abstract

The present invention relates to a laser surface treatment apparatus and method using beam section shaping and a polygon mirror.  In particular, the invention minimizes loss of an attenuated laser beam when radiated onto the polygon mirror by shaping a section of the laser beam with a means, and which can be made compact in size to facilitate maintenance by aligning laser generation means of each surface treatment kit on the same plane (provided that the apparatus has a plurality of surface treatment kits).  The apparatus comprises surface treatment kit (300) including: laser generation means (20) for generating first laser beam (21) having a preset aperture; first beam shaping means (30) for shaping the section of first laser beam (21) to obtain second laser beam (22); second beam shaping means (40) for shaping the section of second laser beam (22) to obtain third laser beam (23); polygon mirror (50) onto which third laser beam (23) is irradiated, said polygon mirror rotating at a constant speed; condensing mirror (60) for condensing third laser beam (23) reflected from polygon mirror (50) to radiate fourth laser beam (24), with the fourth laser beam generating a spot on processing target (100); and means for interwork controlling of transfer speed of processing target (100), output of laser generation means (20) and rotation speed of polygon mirror (50).
