Abstract:
Bright Squeezed Vacuum (BSV) is a non-classical macroscopic state of
light generated through high-gain parametric down conversion. Its mode
structure is rather complicated but worth investigating  because each
mode maintains all nonclassical features and a lot of properties can be
explained in terms of independent (Schmidt) modes. In this talk, I will
present the analytical approach to the theoretical description of BSV in
the frequency domain based on the collective Schmidt operators. This
approach allows one to calculate different characteristics of BSV  and
to predict different new effects including the spectrum narrowing and
achieving a single temporal mode using a dispersive medium.
