Photon echoes generated by long (i.e., 400–800-nsec) frequency-chirped optical pulses are found to possess (after compensating for avoidable material relaxation) up to 25% of the energy of the first excitation pulse and to have a duration determined by the total chirp bandwidth of the excitation pulses. In our experiment, echoes 30 times shorter than the first excitation pulse were observed.
