Query: Two schemes for characterization and detection of the squeezed light:
  Dynamical Casimir effect and nonlinear materials   The detection and characterization of a non-classical-squeezed state of
light, by using two different schemes, will be presented . In the first one, in
an one-dimensional cavity with moving mirror (non-stationary Casimir effect) in
the principal mode, we study the photon creation rate for two modes (squeezed
and coherent state) of driving field. Since the cavity with moving mirror
(similar to an optomechanical system) can be considered analogue to a Kerr-like
medium, so that in the second scheme, the probability amplitude for
multi-photons absorption in a nonlinear (Kerr) medium will be quantum
mechanically calculated. It is shown that because of presence of nonlinear
effects, the responses of these two systems to the squeezed versus coherent
state are considerably distinguishable. The drastic difference between the
results of these two states of light can be viewed as a proposal for detecting
of non-classical states.
