Abstract: A high power Faraday isolator or rotator includes, at least one Faraday optical element, and a magnetic structure capable of generating a magnetic field within the at least one Faraday optical element. The at least one Faraday optical element comprises a Potassium Terbium Fluoride (KTF) crystal grown or manufactured along the [113] crystal orientation and which is oriented such that the light propagating through the Faraday isolator is within 2 degrees of the [113] crystal orientation.

Abstract: A multi-pass-type Faraday rotator useful in an optical isolator is provisioned with high-efficiency, high-field permanent magnets formed with minimal magnetic material. A high magnetic field is generated by two sets of magnets attached to outer pole plates that are mirror images of each other. Like-type poles of the magnets in each set are disposed against each other above and below the beam path plane of a multi-pass Faraday optic. Each set of magnets is formed of a central block of magnetic material with magnetization oriented substantially parallel to the multi-pass beam path on the Faraday optic, adjoined by adjacent blocks of magnetic material with magnetization oriented substantially perpendicular to the central magnet block and with like poles to the central magnet block where the magnets border the multi-pass Faraday optic.
