Abstract
The evolution of the spatial profile of a thermal lens induced by a cw low power laser beam in an absorbing dye solution is directly visualized in real time using glow- coherence light interferometry. Both spatial characteristics and response times of the lens are measured. Preliminary comparisons between experimental result and thermal diffusion theory are presented. The accuracy of measured refractive index in the thermal lens profile is better than 10-6.
