The spectra of resonant Raman scattering of short-period GaAs-AlAs superlattices have been studied experimentally. Resonant Raman scattering processes of up to fourth order have been detected for the first time. The tunneling of electronic excitation in such systems is taken into account in an analysis of the results.
