Faraday Rotator Glass
In high-energy laser devices, in order to reduce the impact of optical feedback on the normal operation of the system, a unidirectional non-reciprocal optical element – an optical isolator – must be added to the optical path to isolate retroreflected light and prevent damage to the upstream optical elements. Faraday Rotator Glass (also known as magnetic faraday rotatory galss) make use of the Faraday rotation effect to rotate the polarization plane when it passes through the material under the action of an external magnetic field. It is the key to devices such as optical isolators, optical modulators, optical switches, and high-current transformers. It also have important application value and economic benefits in major national projects and civil fields.
