Sj. Vanenk et al., EFFECT OF THE CONTINUUM ON ELECTROMAGNETICALLY INDUCED TRANSPARENCY WITH MATCHED PULSES, Physical review. A, 50(3), 1994, pp. 2777-2780
We discuss how transparency and population trapping effects are affect
ed when a realistic continuum is involved. We consider the propagation
of matched pulses in a LAMBDA-like system, where the upper level is r
eplaced by a continuum.
