Ai. Zaitsev et Iv. Ryzhov, Inversionless superradiance of a thin layer of three-level atoms: CoherentRaman transition between sublevels of the lower doublet, OPT SPECTRO, 89(4), 2000, pp. 601-611
The effect of a local field on the transition competition in the process of
superradiance of a thin layer of three-level atoms (Lambda -configurarion
of working transitions) in the presence of an initial coherence of the lowe
r doubler is investigated. It is shown that under the action of a local fie
ld, a coherent Raman transition between sublevels of the lower doublet can
take place. (C) 2000 MAIK "Nauka/Interperiodica".
