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