MODE SUPPRESSION IN THE NON-MARKOVIAN LIMIT BY TIME-GATED STIMULATED PHOTON ECHO

摘要: It is demonstrated that enhanced mode suppression in stimulated photon echo experiments can be obtained by diagonal time gating of the echo. This technique especially important when optical dynamics system non‐Markovian. A two‐mode Brownian oscillator model used to analyze effect on The method a dye solution DTTCI ethylene glycol at room temperature. Experimentally, accomplished means femtosecond phase‐locked heterodyne detected vibrational this are explored conventional experiments. Especially echo‐maximum shift measurements found particularly useful.
