Squeezed states of light are referred to as non-classical field states and are known to be characterized by strong correlations between photons both in the spectral and spatial domain. For these reasons they are very perspective for many important and interesting practical applications in modern quantum optics including storage and transfer of quantum information. From this point of view multiphoton or bright squeezed vacuum states of light generated during stimulated parametric down conversion process with intensive pump seem to be the most attractive.
