✦ Synopsis

A general numerical solution and two approximate analytical solutions ofthe one-dimensional heat diffusion equation are used to calculate the temperature ofa surface exposed to pulsed heating. The calculations simulate the case ofpulsed COz laser heating of fused quartz. The numerical solution (based on a finite difference model ) includes explicitly the temperature dependence of thermal parameters and is in excellent agreement with experimental measurements on the same system. The analytical solutions are unable to rcproducc the temperature history of the sample, and their limitations are discussed.
