Abstract

We have observed the spectrum of electrostrictive stimulated Rayleigh scattering in a liquid and created a transition to stimulated thermal Rayleigh scattering with the addition of an absorbing liquid. With the proper amount of absorption, the electrostrictive and thermal contributions to the scattering exactly cancel, resulting in no stimulated Rayleigh scattering. An absorption coefficient of 0.000 12 cm(-1) is sufficient to cancel the electrostrictive Rayleigh scattering in Freon 113.
