Abstract
A Faraday rotator excellent in productivity and also hardly causing an isolation function of an optical isolator to deteriorate even when the Faraday rotator is used in a high-power laser with a wavelength of 1.1 μm or less and an output of 1 W or more. The Faraday rotator comprises a non-magnetic garnet substrate; bismuth-substituted rare-earth iron garnet films grown respectively on both surfaces of the non-magnetic garnet substrate by a liquid phase epitaxial method; and sapphire crystal substrates bonded respectively to outer surfaces of the bismuth-substituted rare-earth iron garnet films, and configured to dissipate heat. The bismuth-substituted rare-earth iron garnet films has an absorption coefficient of 9 cm−1 or less for light at a wavelength of 1.06 μm, and that the bismuth-substituted rare-earth iron garnet films grown on the respective surfaces of the non-magnetic garnet substrate differ from each other in film thickness by 10 μm or less.
