Enhanced Nonlinear Generation in a Three-Level Medium with Spatially Dependent Coherence
arXiv:quant-ph/0307209 · doi:10.1364/OL.27.001836
Abstract
We consider a method for efficient parametric generation of a laser pulse. A single laser field is injected to a three-level medium which has two lower states and one excited state. The lower states are prepared initially in a position-dependent coherent superposition state. It is shown that by proper choice of the position dependence of the superposition along the direction of propagation, the incoming field can be converted completely to a new field.
