Frequency - Domain Measurements of Spectral Hole Patterns Burned with Phase - Coherent Pulses
C. Michael Jefferson, Alfred Johann Meixner
Several investigations have shown that in some systems stimulated photon echoes may be obtained over times much longer than the excited state relaxation time T11,2. It has been claimed that the mechanism for this anomalously long storage time is the formation of a frequency dependent modulation of the ground state population which persists because of spectral hole-burning1. Such a population grating produced by coherent multipulse excitation and spectral hole-burning has been measured only in a few cases3.
