Rayzer’s High Power Free Space Faraday Rotator(HFR) series product, is an optical device that rotates the polarization of light due to the Faraday effect. Faraday Rotators rotate the plane of polarized light 45° in the forward direction and an additional 45° of non-reciprocal rotation in the reverse direction while maintaining the light’s linear polarization. It is ideal for ultra-fast fiber laser, solid-state laser, multi-level laser amplifier, Optical parametric oscillator Ring laser, Erbium-doped fiber.
