We describe a previously unreported nonlinear scattering effect that occurs in cylindrical liquid jets irradiated by an intense laser pulse. The spatial characteristics of this feature are quite striking: light emanating from a thin (=5 microm) circumferential ring near the cylinder surface. This ring can, depending on the pump intensity, be continuous or periodic in ø. We have observed rings in several liquids (ethanol, water, and carbon disulfide) and, for the case of ethanol, in cylinders ranging from ~14 to ~76 microm in radius. We conclude that the rings are composed of plasma generated by the intense stimulated Raman scattering fields in the cylinder.
