This work presents a detailed study of how the thermal diffusivity measurement of a sample is affected by the deposition of an absorbent layer on its surface, when analyzed by confocal photothermal microscopy. First, the temperature distribution and

An adaptive telescope was developed to perform measurements using the confocal photothermal microscopy technique. The telescope automatically aligns to reinject the reflected probe beam as the measurement scans over irregular surfaces. The system use

An automatic alignment system was developed to extend the capabilities of the confocal photothermal microscopy technique, for non-destructive surface thermal diffusivity measurements, to in situ measurements of non-planar samples. This development al

We study the evolution of the absorptance of amorphous metal oxide thin films when exposed to intense CW laser radiation measured using a photothermal microscope. The evolution of the absorptance is characterized by a nonexponential decay. Different

A photothermal microscope for absorptance homogeneity analysis is described. Absorptance maps with micrometer resolution and high sensitivity are obtained. Changes in absorptance are due to laser annealing of defects via one and two-photon processes.
