Super-bunched bright squeezed vacuum state
In this paper we experimentally study the statistical properties of a bright
squeezed vacuum state containing up to 10^13 photons per mode (10 uJ per
pulse), produced via high gain parametric down conversion (PDC). The effects of
bunching and superbunching of photons were observed for a single mode PDC
radiation by second-order intensity correlation function measurements with
analog detectors.Comment: 4 pages, 3 figures, submitted to Optics Letter
Spectral properties of high-gain parametric down-conversion
High-gain parametric down-conversion (PDC) is a source of bright squeezed
vacuum, which is a macroscopic nonclassical state of light and a promising
candidate for quantum information applications. Here we study its properties,
such as the intensity spectral width and the spectral width of pairwise
correlations.Comment: 9 pages, 5 figure
