Two-mode squeezing of cavity fields
Zhengdong Liu, Xiao-Lin Li, D. L. Lin, Thomas F. George · Physical Review A · 1991
Two-mode squeezing of a cavity field interacting with a three-level \ensuremath{\Lambda}-type atom is found for a field initially in a coherent state. Some phenomena are revealed, such as two-mode squeezing weaker than single-mode squeezing due to the mode coupling, and periodic recovery of squeezed states caused by two-photon processes.
