Abstract

Stimulated Brillouin scattering (SBS) in liquids has generated much recent interest in view of the potential use of developing high-fidelity phase-conjugate mirrors. Unfortunately, the data needed to evaluate the performance of an SBS phase-conjugate mirror for many candidate liquids do not exist or are difficult to find. There has recently been a compilation of some of the properties of several exotic liquids.¹ However, there are no data generally available on the Brillouin shift, linewidth, and peak gain at visible wavelengths for many common liquids transparent in the visible and near IR. We present a comprehensive experimental study of twenty liquids to determine these three parameters at 532 nm, and use standard scaling laws to predict the results at 1064 nm. In addition, we report measurements of the phase-conjugate reflectivity and fidelity for two liquids that are known to have very low absorption¹ in the visible and near IR: SnCl₄ and Freon 113.
