METHOD FOR PRODUCING OPTICAL THIN FILM BY LASER IRRADIATION

摘要

PROBLEM TO BE SOLVED: To suppress a change of the optical characteristics of a thin film with the lapse of time and to produce an optical thin film of good quality at a low cost. ;SOLUTION: The objective method for producing the optical thin film includes a step S2 for forming an optical thin film 2 on the surface of a substrate 1 and a step S3 for irradiating the formed optical thin film 2 with laser light 3.;COPYRIGHT: (C)2001,JPO
