Abstract: The relation between the intensity of photon echo signal and the optical delay time is derived by using the density matrix method. The application to two pulse and three pulse photon echo techniques is given. The transverse relaxation time of saturated iodine gas under regular temperature and pressure is measured experimentally by the two and three pulse photon ehco techniques, and the measurement result is about 140 ps.
