(Note: the conventional symbol for the Verdet constant is: V. To avoid confusion with voltage readings, we switched the symbol to the Greek letter ν.) TGG has twice the Verdet constant of a Terbium-doped glass.

The results show that the rate of change of the Verdet constant at different wavelengths has nothing to do with the Tb3+ concentration, but only with the effective transition wavelength. The effective transition wavelength of the sample was calculated by the formula, and the source of the magneto-optical effect of the rare earth doped magneto-optical glass was confirmed. Another key innovation is glass fiber material itself, a heavily terbium-doped silicate fiber that exhibits a strong magneto-optic: Its Verdet constant is greater than 300 times higher than conventional silica glass. A Verdet constant of 15.18 rad/T/m at 1950 nm with the figure of merit of more than 8.72 rad/T, which is the highest value reported in glass materials at this wavelength, was measured.

The objective of this experiment is to measure and analyze the Verdet constant for Corning 7980, a fused quartz glass with no previously published Verdet constant data. This quartz glass is being used at the Belle II experiment at Tsukuba, Japan. The Verdet constant is measured using the Faraday effect — a magneto-optical phenomenon that describes the rotation of the plane of polarization of

Now, dozens of papers online have said that the Verdet Constant for SF59 is 23rad/Tm, but no actual sources. The Faraday effect can, however, be observed and measured in a Terbium-doped glass with Verdet constant as low as (≈ −20 rad/(T·m) for 632 nm light). Similar isolators are constructed for microwave systems by using ferrite rods in a waveguide with a surrounding magnetic field. A thorough mathematical description can be found here.

The goal of the lab was to measure the Verdet Constant for a sample of light flint glass and to compare its value to a theoretically calculated value. The experimental value was V = (4.13±0.04)·10−6cm −1G while the theoretical value was V = 1.18·10−5cm−1G−1. The Verdet constant is an optical property named after the French physicist Émile Verdet.It describes the strength of the Faraday effect for a particular material.
