Af. Hassan et al., HEATING EFFECTS INDUCED BY A PULSED-LASER IN A SEMIINFINITE TARGET INVIEW OF THE THEORY OF LINEAR-SYSTEMS, Optics and Laser Technology, 28(5), 1996, pp. 337-343
The two-dimensional Laplace integral transform technique is used to so
lve the problem of heating a semi-infinite target induced by the surfa
ce absorption of a laser pulse, Mathematical expressions for the surfa
ce temperature and the temperature profile within the target are obtai
ned considering cooling and temperature-dependent absorption coefficie
nt at the front surface, The linear behaviour of the system is found t
o be established for all cases except for that of temperature dependen
t surface absorptance, As an illustrative example, computations are ca
rried out on Al, Cu, Ag and Au targets using an empirical formula for
the temporal distribution of a measured laser pulse. Copyright (C) 199
