Abstract
The results of an investigation of four-photon parametric superfluores cence under single-pass multibeam noncollinear pumping of the 3D sodiu m level are presented. A significant improvement of the spatial cohere nce of four-photon parametric superfluorescence was experimentally obs erved. The angular structure of the parametric superfluorescence excit ed by a Bessel beam pump is discussed.
