Abstract
Twin-beams generated by non degenerate optical parametric oscillators exhib it squeezing in the intensity difference. Here we report intensity noise co rrelation and single beam spectra for pump power up to 14 times the thresho ld value. The degree of correlation of the two beams is practically indepen dent of pump level. The single beam spectra confirm presence of relaxation oscillation.
