Photon echo modulation effects in cesium vapor
Laser Physics 6:3 (1996) 535-543
Abstract:
Photon echoes are generated on the 6S1/2-6P1/2 transition in Cs vapor with excitation pulses short enough to excite all hyperfine states. As the excitation pulse separation is varied, the temporal profile of the echo reshapes and the time-integrated echo intensity modulates. These effects are typical of all the alkali vapors and provide the simplest, nontrivial display of quantum beating in a four-level system. The present paper describes a detailed experimental study of both kinds of modulation effects and utilizes the billiard ball model to analyze them.
