The primary photon echo signal excited by two non-collinear pulses in optically dense media with extreme inhomogeneous broadening is investigated theoretically and numerically. Non-linear evolution of both echo exciting pulses and echo response during propagation is taken into account. Red frequency shift of the primary photon echo is predicted. The influence of pulse transformation on the echo time delay is analyzed.

In this chapter, we provide a review of early theoretical studies on the photon echo in gases. We derive the basic equations, which will be employed in this monograph for the theoretical description of electromagnetic processes in gas media. For the elementary case when the angular momenta J b , and J a of the upper ( b ) and lower ( a ) resonant levels are equal to 1 and 0, respectively, we analyze the formation of photon echo and stimulated photon echo signals in the case of an inhomogeneously broadened spectral line corresponding to an optically allowed b → a transition. We discuss characteristic parameters involved in the theory of photon echo in gas media.
