Effect of finite pulse duration in three pulse photon echo experiments: Numerical comparison of 3PEPS and S3PE

摘要

Effects of finite pulse duration on two different observables of the three pulse photon echo experiment, the peak shift (3PEPS) and short-time slope (S3PE), are studied by a numerical simulation. The usefulness of S3PE method originally suggested in an impulsive limit turned out to be greatly reduced by finite dura_tion of laser pulses. Some aspects of two experimental scanning methods in the three pulse photon echo experiments are discussed.
