Title

Temperature Distribution Within A Metal Subjected To Irradiation By A Laser Of Spatially Varying Intensity

Abstract

A two-dimensional transient computer model was developed to determine the temperature distribution within a material subjected to irradiation for the intensities required for laser drilling. The purpose of the model was to determine the effect of spatially varying laser intensities on the temperature distribution. The model accounts for both sensible heating and phase changes (solid-to-liquid and liquid-to-vapor) which occur within a metal being irradiated by a laser beam of 10 MW/cm2 intensity with a 10 μs duration and a spot radius of 2 mm. Simulations were conducted for copper and aluminum irradiated using laser beams of fixed energy fluence but with different radial beam profiles.
