Squeezed States in a Cooperative Dicke System
Mark C. Butler, P. D. Drummond · Optica Acta International Journal of Optics · 1986
It is shown that a group of two-level atoms initially in the de-excited state induce squeezing in a coherent single-mode field. This effect occurs at the onset of interaction, and so could be more easily observed than the delayed effect predicted in the corresponding maser system.
