STIMULATED THERMAL RAYLEIGH SCATTERING IN LIQUIDS

In a previous calculation of the gain factor for stimulated thermal scattering, it has been assumed that the dielectric constant is insensitive to changes in temperature. In our treatment such an approximation has not been made and it is shown that this additional contribution gives rise to a correction of up to 6% to the stimulated thermal Rayleigh peak for liquids commonly used in such experiments. The inadequacy of the Lorentz-Lorenz relation in estimating the magnitude of this correction is also discussed. © 1969 The American Physical Society.
