Abstract
We have developed simple analytical methods to estimate the nonequilibrium thermal effects of pulsed nanosecond lasers on carbon-implanted copper substrates. This analytical method eliminates the use of detailed numerical solutions of the one-dimensional heat flow equation with nonlinear moving boundary conditions. The effect of laser variables, especially energy density and pulse duration, on the maximum melt depths, solidification velocities, and maximum surface temperatures have been determined. Comparison between the analytical and detailed computer solutions of heat flow equations have also been performed to determine the validity of these analytical solutions.
