Abstract

TO PROVIDE METHODS OF FORMING A CUTTING START POINT REGION AND CUTTING AN OBJECT TO BE PROCESSED WITHOUT GENERATING MELT OR FRACTURES DEVIATING FROM A LINE TO BE CUT IN THE SURFACE OF THE OBJECT. A LINE TO BE CUT 5 IN A SURFACE 3 OF AN OBJECT TO BE PROCESSES 1 IS IRRADIATED WITH PULSE LASER LIGHT L WHILE LOCATING A LIGHT-COVERGING POINT P WITHIN THE OBJEC 1 UNDER A CONDITION CAUSING MULTIPHOTON ABSORPTION. BY MOVING THE LIGHT-CONVERGING POINT P ALONG THE LINE TO BE CUT 5, A MODIFIED REGION IS FORMED WITHIN THE OBJECT 1 ALONG THE LINE TO BE CUT 5. WHEN THE OBJECT 1 IS BROKEN ALONG THE LINE TO BE CUT 5 BY USING THE MODIFIED REGION AS A START POINT, THE OBJECT 1 CAN BE CUT WITH A RELATIVELY SMALL FORCE. UPON IRRADIATION WITH THE LASER LIGHT L, THE SURFACE 3 OF THE OBJECT 1 HARDLY ABSORBS THE PULSE LASER LIGHT L, WHEREBY THE SURFACE 3 WILL NOT MELT BECAUSE OF THE FORMING OF THE MODIFIED REGION.
