White-light versus discrete wavelength measurements of Faraday dispersion and the Verdet constant

Maxwell, James L; Hughes, Ifan G; Adams, Charles S

Abstract

The wavelength dependence of the Faraday effect may be measured either sequentially at particular wavelengths using narrow band sources, or simultaneously at many wavelengths using a white-light or broadband source. We apply both methods to measure the wavelength dependence of the Verdet constant of a terbium gallium garnet crystal. We show that although the white-light measurement offers the advantage of requiring only one source, it is more prone to systematic errors than using multiple laser sources.
