Abstract

See full text

A method for manufacturing an optical element is a method for manufacturing an optical element in which laser light is transmitted, reciprocated, or reflected, and the method includes a first step of obtaining a bonded element formed by subjecting a first element part and a second element part, both being transparent to laser light, to surface activated bonding with a non-crystalline layer interposed therebetween; and after the first step, a second step of crystallizing at least a portion of the non-crystalline layer by raising the temperature of the bonded element. In the second step, the temperature of the bonded element is raised to a predetermined temperature that is lower than the melting points of the first element part and the second element part.
