Abstract

A method for joining an optical crystal to a substrate includes radiating a pulsed laser beam through the optical crystal or through the substrate onto a surface of an intermediate layer between the optical crystal and the substrate, and forming a fusion zone in the intermediate layer between the optical crystal and the substrate by the radiation of the pulsed laser beam, thereby integrally joining the optical crystal and the substrate.
