Abstract
A single-beam photothermal-lensing technique to study interfaces is present ed. By analysis of the reflection from a quartz-solution interface with a l ow-power laser in a single-beam configuration, a photothermal signal is det ected. The data were fitted with a conventional thermal lens model, and the results show that the optical element formed at the interface resembles an inverted thermal lens.
