Abstract.

Two deflection techniques for the measurement of the dispersive properties of an optical medium have been implemented. Prismatic deflection is used to measure the dispersion of a medium exhibiting Electromagnetically Induced Transparency (EIT) with the \(\rm 5S_{1/2}-5P_{3/2}-5D\) cascade system in 85Rb and 87Rb. In addition, the dispersion associated with a saturated absorption and hyperfine pumping spectrum is measured by deflection due to a spatial inhomogeneity of the refractive index induced by an expanded Gaussian-profile pump beam.
