There are two side-bands in addition to the central fluorescence from dressed atoms in a strong pump field. When two fairly intense pulses at one of the two sideband frequencies are applied to the dressed atoms at time t and t + T, with pulse areas of π/2 and π respectively, an echo is emitted at time T after the second pulse. It is discovered that in addition to the echo with frequency of the applied pulse, there exists another echo at the other frequency of the two side-bands.
