Abstract ：Two six-wave mixing processes are achieved simultaneously in rubidium vapor and two channels are identified. Signal competition between the two channels is observed and phase matching conditions are analyzed for the two channels. The results show that the two six-wave mixing channels correspond to two parametric processes with weak coupling and, moreover, quantum interference and phase matching conditions primarily govern the signal competition.
