The devices based on the Faraday effect, such as Faraday isolators (FI) are the essential components of complex laser systems. Faraday isolators reduce the risk of amplifier self-excitation, protect master oscillator against unwanted feedback, and prevent damage of sensitive elements by back reflections. Recently, there has been an increased interest in high-power laser radiation in the 1.4- 3µm range. Laser radiation in this range is broadly used in industry (welding, cutting, and drilling of plastics), medicine (surgery, urology), in research (material studies, atmospheric probing, environmental monitoring), and is promising for implementing submarine fiber-optic communication. Also, the ~2 µm wavelength range is regarded to be highly promising for the new generation laser interferometers for gravitational wave detection.

Abstract:
Faraday isolators are the essential components of complex laser systems. High-power laser radiation greatly affects the FI characteristics, thereby significantly narrowing the choice of magneto-optical materials. The report provides an overview of promising magneto-optical materials for the manufacture of magneto-optical elements of Faraday isolators operating at the laser radiation ~2µm, results of recent studies of their properties, and some results of the study of the realized Faraday isolators based on such materials.
