Amplitude and phase measurements of femtosecond pulses shaped by use of spectral hole burning in free-base naphthalocyanine-doped films

摘要

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 homogeneous linewidth of 69 GHz) was measured from a photon-echo experiment in the chemically accumulated regime. (C) 2003 Optical Society of America.
