Formation of spatial coherence of superluminescence in a dispersive medium

A theoretical and experimental investigation is reported of the formation of the spatial coherence of superluminescence in dispersive media. The theory is developed in the axial approximation for a given amplitude of a traveling population-inversion pulse. Asymptotic coherence characteristics are obtained for certain important limiting cases. The results are given of an experimental investigation of the spatial coherence of a superluminescent dye laser excited by single picosecond pulses. An analysis is made of the possibility of obtaining short-wavelength superluminescence radiation with a high degree of spatial coherence.

Radiation Trapping in Coherent Media

Andrey B. Matsko, Irina V. Novikova, Marlan O. Scully +1 more

We show that the effective decay rate of Zeeman coherence, generated in a (87)Rb vapor by linearly polarized laser light, increases significantly with the atomic density. We explain this phenomenon as the result of radiation trapping. Our study shows that radiation trapping must be taken into account to fully understand many electromagnetically induced transparency experiments with optically thick media.
