J. Calatroni et al., VISUALIZATION AND MEASUREMENT OF A STATIONARY THERMAL LENS USING SPECTRALLY RESOLVED WHITE-LIGHT INTERFEROMETRY, Optics communications, 138(1-3), 1997, pp. 1-5
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).
