Interference of temporally nonoverlapping light pulses in degenerate four-wave mixing

An interference of the signals of degenerate four-wave mixing excited coherently by two pairs of pulses which do not overlap in time has been observed experimentally for the first time. This interference arises from a superposition of two frequency population gratings which are produced within the nonuniform-broadening line of the working transition by two pairs of pulses.
