High-power Faraday isolator on a uniaxial CeF3 crystal.

Abstract

We have created the first high-power Faraday isolator on an anisotropic magneto-optical element (MOE). The isolator is based on one MOE of a uniaxial CeF3 crystal and ensures an isolation degree of 30dB at a high average laser radiation power of 700W. The limitations due to the anisotropic nature of the crystal do not impose significantly more stringent requirements, either for the beam or the MOE.
