Abstract

PURPOSE:To improve processing accuracy and shorten processing time by applying arch-shape laser spot on an object of processing, with an installation of a light-deflecting mechanism between a laser generator and a conical lens, so that a highly concentrated energy can be applied to an entire circumferencial area of the object of processing with less laser spot.
