Title:
BONDED BODY, LASER OSCILLATOR, LASER AMPLIFIER, AND METHOD FOR PRODUCING BONDED BODY
Document Type and Number:
WIPO Patent Application WO/2019/208658
Kind Code:
A1
Abstract:
In this bonded body (10), a light-transmissive optical material (11) and a cooling material (12) are bonded to each other. At the bonding interface between the optical material (11) and the cooling material (12), atoms contained in the optical material (11) penetrate into and are diffused in the cooling material (12) to an extent such that no interference fringes are generated on the bonded body (10), and the bonded body (10) can transmit light. The length of the penetration and diffusion of the atoms contained in the optical material (11) into the cooling material (12) may be within the range of about 1.0 nm to about 10 µm.
