Description

A highly sensitive and simple photothermal scheme for determining optical absorptions in condensed-matter samples is presented. αl values as low as 10-7 and 10-8 were measured for thin films and coatings and for liquids, respectively. A comparison with the thermal lens effect is given, and the experimental factors limiting our sensitivity are discussed
