发明名称 BESSEL BEAM LASER MACHINING APPARATUS FOR HIGH ASPECT RATE HOLE
摘要 The present invention aims to provide a Bessel beam laser machining apparatus for a high aspect ratio hole, which allows a micro-shape having a high aspect ratio to be processed with high degree of accuracy by performing laser machining using a Bessel beam. The other aim of the present invention is to provide the Bessel beam laser machining apparatus for processing a high aspect ratio hole, which is economical and excellently compatible with an existing apparatus by allowing only a simple optical system to be the necessary composition to perform high aspect ratio machining.
