Abstract

In this Letter, we experimentally study the statistical properties of a bright squeezed vacuum state containing up to ${10}^{13}$ photons per mode (10 μJ 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.
