Quantum theory of nondegenerate four-wave mixing
M. D. Reid, Daniel F. Walls · Physical Review A · 1986
A fully quantum-mechanical theory of nondegenerate four-wave mixing in a system of two-level atoms is presented. The squeezing in the output field from an intracavity four-wave-mixing experiment is calculated. The theory is compared with the recent experimental results of Slusher, Hollberg, Yurke, Mertz, and Valley and strategies to improve the squeezing are suggested.
