摘要:
We show how the pump-induced sharp holes in homogeneously or inhomogeneously broadened absorption line shapes can be used for the production of ultra-slow light. We present a detailed discussion Of underlying concepts and results on the pump power dependences of the group index and the bandwidth-delay product. Further, We discuss experimental results, which are in agreement with theoretical predictions. [GRAPHICS] The variation of group index as function of the intensity of the pump field (S) at different probe detuning delta for in inhomogeneously broadened rare-earth doped crystal.
