Abstract
The spatial profile of a stationary thermal lens induced by a cw low p ower laser beam in an absorbing dye solution is directly visualized in real time using spectrally resolved white light interferometry. Spati al characteristics of the lens are measured. Comparison between experi mental results and thermal diffusion theory is presented. The accuracy of the measured refractive index in the thermal lens profile is about 10(-6).
