Paper Abstract

Absorption characteristics of optical coatings have been observed using infrared photothermal radiometry as a noncontact diagnostic technique. The local laser-induced temperature rise was measured as a function of position on the coatings. The data was used to calculate the absorption of the coatings and to identify point sites with atypical absorption. The coating samples were tantala/silica multilayers designed to be high reflectors at 1.32 micrometers . The tests were done with a 1.32 micrometers , continuous-wave Nd:YAG laser and a HgCdTe infrared camera.
