WebCoherent microwave stimulated emission in a cavity is analyzed for the case of alkali atoms under coherent population trapping. The coupling of the atoms to the microwave field generated inside the cavity by the atomic ensemble is taken into account. Moreover, relevant density and propagation effects are described. WebDec 3, 2010 · Coherent trapping in three level lambda and ladder systems is examined for the case of two fluctuating laser fields with unequal bandwidths, obtained by frequency multiplying methods. The inclusion of uncorrelated laser fields destroys trapping and washes out the narrow coherence hole in the fluorescent intensity.
