Summary form only given. The investigations of nonlinear processes in various media pumped by Bessel beams are of broad interest due to the directivity of generated radiation. In this paper we present the results of an experiment, where the essential modification of angular structure of the four-photon parametric superfluorescence is demonstrated in sodium vapour pumped by two Bessel beams of different frequencies.
