Unsteady-State Heating of a Finite Disc by Continuous and Repetitively Pulsed Laser Radiation

Abstract

The heating of a solid body by a laser beam has been analyzed using a generalized two-dimensional solution of the heat conduction equation for a finite right circular cylinder. This series-eigenvalue solution includes time- dependent flux boundary conditions and reradiation from all surfaces. Temperature solutions are derived for three spacial laser beam profiles applied to continuous wave, pulsed, and repetitively pulsed laser heating. Computer programs developed to evaluate these temperature solutions are presented.
