Direct Calculation of Optimized Laser Power Density Profiles for Laser Heating

摘要

Laser surface heating requires a well defined temperature profile. In this paper the inverse problem of heat conduction in solids is solved, based on the two-dimensional Fourier transform. That is, the required power density profile of the laser beam can be calculated directly from a desired temperature field. Problems and errors introduced by calculations on a finite grid and by physically impossible temperature gradients are addressed to
