1950 nm 45°Faraday Rotators

Faraday rotator is a device that realizes precise non-reciprocal rotation of laser polarization. It provides non-reciprocal rotation while maintaining the linear polarization of the beam. In combination with a polarizer, it can block the return light in the optical path and realize a device that realizes precise non-reciprocal rotation of laser polarization. Faraday rotators provide non-reciprocal rotation while maintaining the linear polarization of the light beam. When light passes through the Faraday rotator in a certain direction, the polarization state will rotate 45°; when the light beam passes through the Faraday rotator in the opposite direction, the polarization state will rotate another 45° in the same direction relative to the magnetic field. Based on this principle, in combination with a polarizer, the return light in the optical path can be blocked. The Faraday rotator we provide is made of magneto-optical crystal with high Verdet constant and low absorption coefficient, with high reliability and small M2 degradation. Combined with high damage threshold technology, the average power of the product can reach 500W Max., with a wavelength range of 355 nm-4500nm.
