Linear response functions or Green functions are derived for the acoustic vibrations which propagate perpendicular to the surfaces of a parallel-sided slab, and the corresponding power spectra of the acoustic displacement-gradient components are determined. The frequency dependence of the normal-incidence Brillouin-scattering cross-section is calculated for arbitrary relative sizes of slab thickness, acoustic mean-free-path, and optical absorption length. Various limiting cases of physical interest are studied.
