Faraday rotator is a series of Faraday rotators independently developed and designed by the company, which uses high-quality magneto-optical crystals, with high transmittance, anti-optical damage threshold and other properties, and can be applied to solid-state lasers, fiber lasers, semiconductor lasers and optical measurement equipment and other equipment.
Faraday rotator is a non-reciprocal magneto-optical device based on Faraday effect, which can rotate the polarization direction of incoming ray polarized light by a certain angle, generally set to rotate 45°; The direction of rotation of the light is only related to the direction of the internal magnetic field, and when the beam passes through the Faraday rotator in the opposite direction, the polarization state of the light will rotate 45° in the same direction; The Faraday rotator works with a polarizer to block the return light in the optical path and realize the one-way passage of light. The magneto-optical isolator is mainly composed of three parts: polarizer, Faraday rotator and polarizer. The magneto-optical isolator launched by our company is a polarization-dependent isolator that can effectively block the returned light and protect the laser device.
The Faraday rotator and magneto-optical isolator series products independently developed and designed by Yong Hee are made of high-quality magneto-optical crystals, which have high transmittance and anti-optical damage threshold, and can be applied to a variety of laser equipment. The light height and size of the product are the same as similar products on the market, with a variety of models, and more needs can be customized. In addition, our company provides fluoride magneto-optical crystal products, which have the advantages of low thermal effect and can maintain good performance at high power.
Product application: It can be used in solid-state lasers, fiber lasers, semiconductor lasers, and optical measuring devices.
