Abstract

We measure the second- and third-order dispersion coefficients, d2k/ dω 2 and d3k/dω3, of water for wavelengths from 0.45 to 1.3 μm using a Michelson white-light interferometer. In this interval, the second-order dispersion ranges from 0.068 to -0.1 fs2/μm, and the third-order dispersion ranges from 0.048 to 1.18 fs3/μm. We observe an oscillation in d2k/dω2 near 1.1 μm that is due to water absorption features near that wavelength. From the dispersion coefficients, derivatives of the index of refraction of water are calculated and compared with available equations. These measured values of d2n/dλ2 and d3n/dλ3 should be useful in the evaluation and improvement of existing equations for n(λ) in water.
