Webentered before reflection. In the Faraday effect, however, the direction of the optical rotation, as viewed when looking into the beam, is reversed when the light traverses the substance opposite to the magnetic field direction; that is, the rotation can be reversed by either changing the field direction or the light direction. WebMay 2, 2024 · A Faraday rotator (FR) and two polarizers (P 1, P 2) composed an isolator that prevented the backward laser from entering the laser resonator. A half-wave plate λ/2 and a polarizer P 3 were used together as a variable attenuator to adjust the energy of the pump. An SBS single-cell compressor was adopted in this experiment.
