The article gives the results of a study of the effect of He buffer gas on nonlinear processes during two-photon excitation of rubidium vapor. In addition to four-photon parametric luminescence and a stimulated four-photon parametric process, lines of two-photon decay and stimulated electronic Raman scattering, not previously observed in rubidium vapor, have been obtained. The dependences of these processes on the pressure of the buffer gas and on the frequency of the exciting radiation are investigated and discussed.
