Intense ultrashort laser beam, after propagation through a transparent medium (water in this work), experiences self-focusing, thereby increasing the intensities in localized area to such high values so as to induce nonlinear optical effects like the generation of white light super-continuum and multi-photon absorption. We have carried out experiments for measuring super-continuum generation in water that contains ultra dilute solutes (of ethanol). Our observations of generation of super-continuum spectra in various solutes indicate that our measurements are able to make a distinction between normal water and water mixed with such ultra-dilute solutes i.e. Homoeopathic medicines.
