Keywords: verdet constant, diamagnetic glass, faraday effect. E-mail address: k_thamaphat@hotmail.com. Page 2. INTRODUCTION. 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 Nov 28, 2009 does or does not vary as a function of wavelength or glass sample. The Abbe number (not to be confused with the Verdet constant, Jul 18, 2019 Verdet constant describes the strength of Faraday Effect for a particular material.

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.) The symbol ν is defined as the Verdet constant. For the SF-57 glass rod sold with the TeachSpin apparatus, the Verdet constant for 650 nm light is 23 rad/Tm.

Abstract:. Fe3O4 nanoparticles were synthesized and doped into two glass systems (Na2O-B2O3 glass and PbO-Bi2O3-B2O3-GeO2 glasses) at low concentrations using traditional glass melting method.

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. TGG (Terbium Gallium Garnet) single crystal is currently the best and widely used magneto-optical material in Faraday rotator and isolator due to its extremely high Verdet constants in the range of 400nm-1100nm(excluding 475-500nm). From a linear ﬁt to the data and using Eq. 3 , a Verdet constant of 29.37±0.96rad T −1m is obtained.

The wavelength and temperature dependencies of the Verdet constants of samples have been investigated in the ranges of 400 to 800 nm and 100 to 300 K. The results show field, verdet constant. Introduction he phenomenon of Faraday Effect was first discovered Michael Faraday in 1845. He discovered for the concrete evidence for the relation between the branch of Optics, magnetism and atomic Physics. He found out that when a block of glass is subjected to a strong magnetic field, it becomes Verdet Constant V (min/Oe.cm): 632.8nm-0.258-0.361: Verdet Constant V (min/Oe.cm): 1064nm-0.075-0.106 I CANNOT find a reference for the Verdet Constant of SF59 glass at 650nm (found V for many other wavelengths). I have searched for hours and hours, checked through 4 different CRC handbooks, and can't find a source to cite.

In optical ﬁber, the core and cladding have different Verdet constants, since they are made of different materials. Only a portion of the guided mode exists in The Verdet constant is as large as 0.200 min G −1 cm −1 at 980 nm for 22.5GeS 2 –67.5Sb 2 S 3 –10PbI 2 composition glass, which is the largest value reported thus far for sulfide glasses; this glass also possesses good thermal and optical properties and therefore might be an attractive candidate for mid‐infrared magneto‐optical device applications. Faraday Effect Rotation for Water and Flint Glass. This experiment is designed to measure the Verdet constant V through Faraday effect rotationof a polarized laser beam as it passes through different mediums, Flint Glass and water,.

Exp-3 Verification of the relationship between Verdet's constant and wavelength. The Verdet Constant \is de ned as the rotation per unit path per unit eld strength." [3] It also acts as a proportionality constant between the angle of rotation and the product ofthemagnetic eldandpathlengththroughthesample. The goal of the experiment was to measure the Verdet Constant for the light int glass sample and compare it Verdet constant for the diamagnetic glass using Faraday effect and compare it to a theoretically calculated value. MATERIALS AND METHODS To check the Verdet constant for the diamagnetic glass, Schott’s SF 6 glass, which is a dense flint containing over 70% by weight lead oxide, was used as a sample. It is commonly used 1991-11-01 2018-06-15 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. Deep-ultraviolet (DUV) light sources are critical owing to their high photon energies and small diffraction limits, and synthetic quartz glass (SQ) is suitable for the Faraday rotators of DUV light.
