LASER BEAM PRECISION MACHINING METHOD FOR TRANSPARENT MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a laser beam machining method capable of precisely and efficiently eliminating the damage of diamond etc., and to solve the problems of a machining cost and machining accuracy by using an inexpensive and easy-to-handle laser wavelength of particularly a YAG laser etc.

SOLUTION: The laser beam precision machining method for an optical medium comprising machining the optically transparent medium by introducing a light absorption layer into the surface layer or the inside thereof and irradiating a laser beam toward the light absorption layer, the laser beam precision machining method for the transparent medium comprising forming electrodes or wiring by subjecting the optically transparent medium to grooving or changing the properties of the medium and the laser beam precision machining method for the transparent medium comprising forming a colored layer by introducing boron or phosphorus etc., into the optically transparent medium during the vapor phase growth thereof and irradiating the colored layer with the laser beam, are provided.
