PURPOSE:To carry out a cutting work on a transparent material into a complex configuration by radiating a high energy beam, which is not absorbed into the transparent material, inside of the transparent material while focusing the beam. CONSTITUTION:A high energy beam, which is not absorbed into a transparent material, is radiated inside of the transparent material through an optical system constituted from lenses or mirrors while focusing the high energy beam. Thereby, an extremely small crack of not more than several ten microns is generated at a point where the high energy beam has been radiated. While moving the radiating position by this high energy beam, the consecutive crack is generated in the transparent material so that a cutting work on the transparent material can be carried out. |
