Paper Abstract

We calculate the transient and steady state temperature field of CO2 laser conditioning of fused silica using thermal transporting model. We find that surface temperature at the beam center grows rapidly at the initial heating stage both for the linear thermal transport and nonlinear heat transport, then grows very slowly approaching the stationary value. The axial thermal gradients of nonlinear thermal transport, accounting for the increased thermal conductivity at high temperature, are more smooth than those of the linear case.
