Abstract:
Calculations are presented which describe the temperature distribution resulting from a rapidly scanning laser beam over the target surface. The energy absorbed in a thin surface layer produces a surface temperature increase. The resulting temperature increase is calculated as a function of time for a number of significant scanning and target material parameters.
