Ja. Vaccaro et al., STOCHASTIC WAVE-FUNCTION DIAGRAMS FOR ELECTROMAGNETICALLY INDUCED TRANSPARENCY, INVERSIONLESS GAIN AND SHELVING, J. mod. opt., 45(2), 1998, pp. 315-333
A rigorous diagrammatic description of stochastic wavefunction evoluti
on for electromagnetically induced transparency (EIT) and inversionles
s gain in coherently driven three-level systems is developed and appli
ed to transient and steady-state conditions. Wavefunction trajectories
are illustrated for cases that include Lambda and V-type EIT, shelvin
g and dressed-state resonances.
