Abstract
The unconditionally squeezing of the collective spin of an atomic ensemble in
a laser driven optical cavity (I. D. Leroux, M. H. Schleier-Smith, and V.
Vuletic, Phys. Rev. Lett 104, 073602 (2010)) is studied and analyzed
theoretically. Surprisingly, we find that the largely detuned driving laser can
improve the scaling of cavity squeezing from $S^-2/5$ to $S^-2/3$, where S
is the total atomic spin. Moreover, we also demonstrate that the experimental
imperfection of photon scattering into free space can be efficiently suppressed
by detuning.
