Waves in intensity coherence of evolving intense twin beams

Abstract

Strong correlations between the signal and idler beams imprinted during their generation dominantly determine the properties of twin beams. They are also responsible for the waves in intensity coherence observed in the wave-vector space of a twin beam propagating in a nonlinear crystal in the regime with pump depletion. These waves start to develop at certain twin-beam intensity and move from the signal and idler beam centers towards their tails. They manifest themselves via the change of coherence volume monitored in the far field by the measurement of local modified ${\bar{g}}^{(2)}$ function, which acts as a sensitive and stable tool for investigating field intensity coherence.
