Abstract

The complete waveforms of 1.4 µs optical signal pulses are delayed and stored using a coherently prepared warm Rb vapor, and then recovered up to 500 µs later (with a factor of 2 temporal pulse broadening). Mediated by four-wave mixing, frequency-shifted idler pulses are generated, and then stored and retrieved simultaneously with the signal pulses. The intensities of the retrieved pulses depend linearly on the intensity of the retrieving coupling beam.
