Abstract
A mathematical formalism based on the classical theory of Brillouin scattering with non-monochromatic incident radiation is developed and used to account for the effect of radiation linewidths on the spectral resolution of the pump-probe technique (PPT) in application to the Brillouin spectroscopy. Theoretical findings are verified by comparison with corresponding experimental PPT data from an earlier study on , a paradigm of SBS, which is well documented for its acousto-optical properties.
