Abstract

The effect of a local field on the transition competition in the process of superradiance of a thin layer of three-level atoms (Λ-configuration of working transitions) in the presence of an initial coherence of the lower doublet is investigated. It is shown that under the action of a local field, a coherent Raman transition between sublevels of the lower doublet can take place.

Effect of the near-lying level on the kinetics of populations in the superradiance of a thin layer: Local-field regime

А. И. Зайцев, Igor Viktorovich Ryzhov

The effect of the local field on the competition of transitions in the superradiance of an incompletely excited thin layer of three-level atoms Λ-diagram of working transitions) is studied. The analysis made proves that the upper sublevel of the lower doublet is initially unpopulated. It is shown that the Raman transition, in the local-field regime, is ahead of the development of the superradiance pulse and causes the transfer of populations between sublevels of the lower doublet.

We investigate the influence of the local field on the competition between the operating transitions in the superradiant emission from a thin film comprised of the three-level atoms with the initial coherence of lower doublet. Due tot this influence a coherent Raman transition between the sublevels of a doublet may occur.

Effect of the near-lying level on the kinetics of the field of superradiance of a thin layer

The effect of the local field on the competition of transitions in the superradiance of an incompletely excited thin layer of three-level atoms (Λ-diagram of working transitions) is studied. Analysis is made for the conditions when one of the sublevels of the lower doublet is initially unpopulated. For an initially unpopulated upper sublevel of the lower doublet, a new superradiance regime is found.

Under analysis is the influence of the local field upon the competition of transitions in the process of superradiance from incompletely excited thin layer of three level atoms ((Lambda) -diagram of the operating transitions). It is highlighted that while the upper sublevel of the lower doublet starts degenerating, there is a superradiant regime, where the combinative transition leads the development of the superradiance pulse, and the time of the pulse delay depends on the parameters of the local field and splitting of the lower doublet.

We analyze the possibility of superradiance in an ensemble of three-level atoms in the absence of population inversion. We show that in the case of a Λ configuration of the active transitions this effect can occur for an initially coherent superposition of the states of the lower doublet. We also study how splitting of the lower levels influences this effect and discuss ways of creating low-frequency coherence.
