Abstract

The technique for high precision measurement of optical absorption and adsorption is proposed. The technique is based on the laser interferometric calorimetry method. The mathematical model for estimation of thermal fields which occur in the sample at partial absorption of high-power laser radiation is elaborated. The model considers influence of volumetric and superficial optical absorption coefficients. Sensitivity of measurement technique of absorption coefficients for optically transparent materials is (10^-3 divided by 10^-7) cm^-1. The results of experimental tests of optical material for visible spectrum are shown.
