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.

The Verdet constant is wavelength dependent and for SF-59 glass is advertised to be 23 rad/m·T for 650 nm light. Verdet Constant V (min/Oe.cm): 632.8nm-0.258-0.361: Verdet Constant V (min/Oe.cm): 1064nm-0.075-0.106 The Verdet constant of the magneto-optic glass can be written as (4) V = V para + V diam Where V para is the paramagnetic part and V diam is the diamagnetic part of the Verdet constant. When the paramagnetic component in the glass dominates, the magneto-optic glass as a whole is paramagnetic. field component in the direction of the light propagation and V is the Verdet constant for the material (MKS units: radian/Tesla meter). This empirical proportionality constant varies with wavelength and temperature and is tabulated for various materials. The Verdet Constant, V, depends on the dispersion of the refractive index, dn/d where n 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. I CANNOT find a reference for the Verdet Constant of SF59 glass at 650nm (found V for many other wavelengths).

Magneto-optical properties of tellurium-arsenic-selenium glass (Te 20 As 30 Se 50) were measured and analyzed.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. From the values of slopes for Glass and water, 13.93±0.08 and 59.67±0.53 respectively, the values of Verdet constants for both can be obtained. The Verdet constant for glass is 1.79 × 10 − 5 rad Gcm . and for water is Verdet constant differs from the value measured from the bulk samples. The Verdet constant experienced by light in an optical ﬁber is different from that in bulk glass. In optical ﬁber, the core and cladding have different Verdet constants, since they are made of different materials.

So, a 3 A current supplied to the solenoid will produce a rotation of a little less than 5° in the plane of a polarized light beam at 650 nm with SF-59 glass. 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. For a constant magnetic field parallel to the path of the light, it can be calculated by: = Where is the angle between the starting and ending polarizations, is the Verdet constant, is the strength of the magnetic flux density, and 2020-04-01 The angle of rotation is given by θ = V l B, where V is the Verdet constant of the glass (given in radians/m·T), l is the length of the glass rod, and B is the magnetic field.

and a constant known as the Verdet Constant. 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.

A linear relationship is also established between the Verdet constant and �� 𝜆 where λ is the wavelength and n is the index of refraction for the glass rod.

Faraday effect: determining Verdet’s constant for flint glass as a function of the wavelength Add to product list This product is classified as a dangerous good and is not available for online purchase. 2018-06-15 · The Verdet constant of the magneto-optic glass can be written as (4) V = V para + V diam Where V para is the paramagnetic part and V diam is the diamagnetic part of the Verdet constant. When the paramagnetic component in the glass dominates, the magneto-optic glass as a whole is paramagnetic. Faraday rotator glasses with high Verdet constants are used for optical isolators and sensors. Based on the Tb 2 O 3 -B 2 O 3 -Al 2 O 3 - SiO 2 system and the effect of each component on glass formation, glass compositions were selected for development of new Faraday rotator glasses.

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 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.

For SF-59 glass, the Verdet constant (at 650 nm) is 23 rad T −1 m −1. Assuming the glass rod is 0.15 m long, θ will be 0.086 rad or 4.9°. So, a 3 A current supplied to the solenoid will produce a rotation of a little less than 5° in the plane of a polarized light beam at 650 nm with SF-59 glass.
