Abstract
A high-energy laser Faraday rotator is used in an optical system in which the Faraday rotator absorbs laser light energy of more than 20 mW. The Faraday rotator includes a bismuth-substituted rare-earth iron garnet single crystal film grown as a Faraday rotator by using a liquid phase epitaxial method, and non-magnetic substrate having a side surface on which the bismuth-substituted rare-earth iron garnet single crystal film is formed.
