Photon Echo Measurements in Liquids Using Pulses Longer Than the Electronic Dephasing Time
We present three pulse stimulated photon echo peak shift measurements on several polar protic and aprotic solvents using 22 and 90 fs pulses. Measurements with both pulse durations reveal distinct ultrafast (<100fs) incipient relaxations followed by identical decays after about 300 fs.
