Faraday Rotator
Faraday rotator is a magneto-optical device based on the Faraday magneto-optical effect. When the beam enters forward, the Faraday rotator rotates the linearly polarized light θ. After this beam of light is reflected into the Faraday rotator, the polarization direction of the light is rotated again, and the rotation direction is the same as that of the light entering the forward direction. At this time, the polarization direction of the outgoing light is rotated by two relative to the incident light θ. This can effectively reduce the interference effect between incident light and reflected light to reduce the impact on …
