FARADAY-EFFECT IN TIO2-SIO2 GLASSES

The Faraday effect in TiO2-SiO2 glasses was monitored by a previously proposed dynamic method. For silica glass (Suprasil 2), the evaluated Verdet constants for wavelengths of 632.8 and 785 nm were found to be (3.930 +/- 0.017) X 10(-6) and (3.237 +/- 0.068) X 10(-6) (rad/A), res pectively. The Verdet constants of ULE glass (Corning, Code 7971) at 6 32.8 and 785 nm were (3.836 +/- 0.064) X 10(-6) and (3.297 +/- 0.073) X 10(-6) (rad/A), respectively. With the determined refractive indices , the wavelength-dependent Verdet constant of silica glass was calcula ted from 213.856 to 6725 nm with the derived equation by means of disp ersion theory.
