Abstract

Results of a theoretical investigation of instabilities in a resonant, coherently pumped, homogeneously broadened three-level system are presented. It is found that the behaviour of this system is significantly different and apparently much less complex than that of an incoherently pumped two-level system under similar conditions. In the absence of pump-field induced Rabi splitting, the emission is stable even when relative excitation is very high while presence of such splitting is found to lead only to regular pulsations. © 1986.
