STIMULATED BRILLOUIN SCATTERING.

Abstract

The characteristics of the Stokes light and the hypersound generated by the stimulated Brillouin scattering of ruby laser light in various liquids and fused quartz at room temperature are studied in detail experimentally. In the case of nonfocusing liquids such as n-hexane, methanol, and carbon tetrachloride, it is found that at room temperature the measured characteristics of the Stokes light agree well with calculated results obtained on the basis of the steady-state theory; all the constants needed in the calculation are available from completely independent measurements. A similar study is made of fused quartz at room temperature. The results on the Stokes intensity is also used to estimate the attenuation constant of the 24 GHz hypersound in fused quartz at room temperature; it is 280/cm. In addition, the hypersound is detected and the spatial distribution of its intensity is measured by means of Bragg-diffraction of a He-Ne laser beam. In addition, a brief review of the steady-state theory of the stimulated Brillouin process is also given. (Author)
