The theoretical analysis of the transverse phase-matching conditions for th
e first Stokes and first anti-Stokes radiation in stimulated Raman scatteri
ng by a Bessel beam is provided. The experimental results of the observatio
n of the first Stokes and first anti-Stokes angular spectra in the acetone
pumped by a Bessel beam at lambda(p) = 532 nm are presented, and good agree
ment with the theoretical predictions is obtained. (C) 1999 Published by El
