Stimulated emission from single quantum dipoles
... where d , , is the dipole matrix element. In deriving this result, the two-level system is assumed to have a spatial extent small in comparison to the optical wavelength so that the dipole approximation is applicable. In particular, the spatial variation of the optical wave is rcmoved from the inter ...
