We performed pulse-shaping and time-reversal experiments using spectral holography based on persistent spectral hole burning in free-base naphthalocyanine-doped films. We demonstrate that we can control the pulses diffracted from the hologram by shaping and then by characterizing these pulses in both amplitude and phase. A dephasing time of 29 ps (i.e., a(More)
A photon echo experiment in Tm(3+):YAG is reported that shows, for the first time to the authors' knowledge, the time-domain equivalent of the transition from near- to far-field diffraction, including Talbot self-imaging effects. The experiment demonstrates the huge dispersion capability of photon echoes and opens the way to further exploration of(More)
