In-vacuum Faraday isolation remote tuning [PDF]

Applied Optics, 2010
In-vacuum Faraday isolators (FIs) are used in gravitational wave interferometers to prevent the disturbance caused by light reflected back to the input port from the interferometer itself. The efficiency of the optical isolation is becoming more critical with the increase of laser input power.

Extensive study of magneto-optical and optical properties of Cd1−xMnxTe between 675 and 1025 nm

AIP Advances, 2023
We determine Faraday rotations and measure the optical reflection and transmission from magneto-optical Cd1−xMnxTe crystals with various stoichiometric ratios. For wavelengths between 675 and 1025 nm, we derive Verdet constants, optical loss coefficients,
