In this paper, we propose a scheme to control various electromagnetically induced two-photon transparencies in Rb vapor. Atomic Rb is considered as a five-level quantum system. We employ four lasers, one of which is tunable from standing to travelling wave, and we investigate four-wave mixing processes. We consider two scenarios in which either one or two two-photon transitions are allowed. We find several tunable two-photon electromagnetically induced transparencies.
