    Abstract

    A simplified method of analyzing laser rate calorimetry on samples with absorbing coatings is presented. Special cases of rate calorimetry are shown to agree with previously derived cases. Results are given for samples with dissimilar faces in which the temperature rise and the reflected power in both orientations to the laser beam are measured. A computer program was written to reduce data. A sample case shows that the output requires the reflected and transmitted powers to be measured to three significant figures for meaningful results.
