This phenomenon is used to separate the input and output beams in regenerative amplifiers.
This phenomenon is used to separate the input and output beams in regenerative amplifiers. This effect's "figure of merit" is inversely proportional to the absorption coefficient and can be tuned by doping in rare earth garnets like yttrium iron garnet or terbium gallium garnet. This effect is the theoretical basis behind optical isolators. This effect can be derived by solving the equation of motion for an electron in a longitudinal field and noting that the result contains two terms which correspond to left-handed and right-handed circularly polarized light waves travelling at different phase velocities. The strength of this effect is equal to the product of the path length, the B-field strength, and the Verdet constant. For 10 points, name this magneto-optic effect in which a linearly polarized light beam traveling in a region with a magnetic field undergoes rotation of its plane of polarization.
