Abstract

A novel two-wavelength one-path nonlinear interferometer is used to measure refractive-index dispersion for a number of molecular gases. Δn, is measured directly, where Δn = n - nω with ω = 2πc/694 nm. Δn was measured for these gases previously. For CH4, the results are consistent with conventional refractive-index data from the literature; for CHF3, CH3F, CF4, and SF6, these results improve refractive-index data for wavelengths shorter than 400 nm; and, for CH2F2, these results provide the only data on dispersion available to our knowledge.
