Paper Abstract

Unexpected rise of longwave band magnitude observed in photoacoustic (PA) spectrum obtained for the YAG:Cr laser material is discussed. Explanation of this phenomenon is proposed based on comparison of measured and calculated photoacoustic signal dependence on modulation frequency. Finite lifetime of excited level has been taken into account for this reason. Contribution of PA signal generated after absorption of sample luminescence by walls of measuring cell has been considered.
