OptoCity - TGG & Faraday Rotator
WebIn general, an index of refraction is a complex numberwith both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength—thus, the imaginary part is sometimes called the extinction coefficientk{\displaystyle k}. Terbium gallium garnet (TGG) is a kind of synthetic garnet, with the chemical composition Tb3Ga5O12. This is a Faraday rotator material with excellent transparency properties and is very resistant to laser damage. TGG can be used in optical isolators for laser systems, in optical circulators for fiber optic systems, in optical modulators, and in current and magnetic field sensors. TGG has a high Verdet constant which results in the Faraday effect. The Verdet constant increase… definition of discrimination uk
TGG( Terbium Gallium Garnet) for Faraday Rotator & Isolator
WebThe refractive index, the temperature coefficient of the refractive index, and the optical transparency of gadolinium gallium garnet are reported as a function of wavelength from the near UV to the middle IR. The material is transparent enough for good optical components between 0.36 and 6.0 μm, and the refractive index ranges from 2.0 at the UV end to 1.8 at … WebThe Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as v = c / n (1) where v = velocity of light in the medium (m/s, ft/s) c = speed of light in air or vacuum - approximately 3 108 m/s (or 299792458 m/s) n = refractive index WebTGG is an excellent magneto-optical crystal used in various Faraday devices (Rotator and Isolator) in the range of 400nm-1100nm, excluding 475-500nm.It has large magneto-optical constant, low light loss, high thermal conductivity and high laser damage threshold. ...
