Abstract

We present dispersion curves for aqueous media measured with a white-light interferometric technique. Data is presented for wavelength ranges in the visible and near IR. Materials investigated include high purity water and primate vitreous. Results are examined with regard to retinal damage mechanisms associated with ultrashort laser pulse exposures. In this pulse duration regime the dispersive nature of the medium can play a critical role in predicting damage thresholds. These values are also critical to the development of nonlinear propagation models. We compare our results to other measurement techniques which determined index of refraction at a series of single wavelength points. Results indicate that he dispersive trends in the materials can be quickly and accurately mapped over a wide spectral range using this technique.
