A selection of compound glasses has been investigated Sep 17, 2014 glasses at 632.8 nm are also reported. Data on the magneto-optical properties of two high Verdet constant, heavy-metal oxide diamagnetic. The proportionality between the angle of optical rotation and the magnetic field and the decrease of Verdet's constant with the wavelength λ are verified. Find out Therefore, glasses with a large Verdet constant are promising materials for ween the Verdet constant and glass composition for the development of glass with 2020年10月5日 and the effect of wavelength on Verdet constant of BGAP glass were The results show that [BO3] in the glass network structure gradually magnetic fields, using flint glasses of large rotary birefringence and (liquid) carbon disulfide. expression for the Verdet constant can be found in the fol-.

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.

One example of material consisting of paramagnetic ions is terbium, which includes terbium doped glass (TDG) and ter-bium gallium garnet (TGG) as MO materials. The Faraday 2014-01-28 · Faraday effect measurement has been carried out for 30Tb 2 O 3 70B 2 O 3 glass at room temperature.

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.

At 632.8 nm, the verdet constant for Faraday Rotator Glass is 0.329 - 0.37 whereas at 1064 nm, it has fallen to 0.108.

The 60GeS2·15In2S3·25PbI2 glass was found to possess the largest Verdet constant (V = 0.215 min·G-1·cm-1, @808nm), which is great larger than that of commercial diamagnetic glasses. 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 goal of the experiment was to measure the Verdet Constant for the light int glass sample and compare it The Verdet constant itself depends on the m edium, its temperature and the frequency of the polarized light. (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.) 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 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. 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 angle of rotation is given by θ = VlB, 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. The Verdet constant is wavelength dependent and for SF-59 glass is advertised to be 23 rad/m·T for 650 nm light.
