Three-dimensional temperature distribution in laser heated solids

摘要

In this paper we extend a thermal model of the laser interaction with solids .The previous model (Appl.Phys.B 71,523-531 , (2000)) takes into account Gaussian laser beams and calculate the temperatures only at the center and at the corner of the input face. In the present paper we extent the model for three dimensional temperature profiles and take into account a explicit surface absorption. We will apply the model at CO_2 laser interaction with optical components (ZnSe).
