Temperature response in absorbing, isotropic scattering medium caused by laser pulse

On the basis of our previous papers (H.P. Tan, B. Maestre, M. Lallemand, Journal of Heat Transfer 113 (1) (1991) 166–173; H.P. Tan, T.W. Tong, L.M. Ruan, X.L. Xia, Q.Z. Yu, Int. J. Heat Mass Transfer 42 (1999) 2967–2980), the radiative source term in absorbing, emitting, isotropic scattering medium, caused by collimated incidence through semitransparent boundary, is deduced in this paper. With some different sorts of boundary conditions, optical, spectral, and scattering characters, the transient temperature response, produced by a short-time laser pulse irradiating the surface of a semitransparent medium is simulated. The simulating results show that coating the non-incident side of medium with strongly absorbing material and selecting suitable incident wavelength, can increase the excess temperature of the non-incident surface, or can reduce the incident radiative intensity if keeping the excess temperature identical to that without coating or with coating both sides of the medium, and so, the probability of producing non-Fourier effect may be reduced.
