Abstract

Pulsed photothermal radiometry (PPTR) method based on analysis of experimentally measured kinetics of non-equilibrium infrared blackbody (thermal) emission from a specimen subjected to pulsed laser irradiation has been used to investigate optical properties of tissues. Detailed investigations of thermal emission kinetics and the relationship caused by pulsed YAG:Er and YAG:Ho laser irradiation of tissues with different pulse duration and over a broad energy range up to the evaporation threshold have been performed. The spectrum of dentine in the IR region is presented.
