    "abstract": "We study the spatial correlations of quantum fluctuations that can be\nobserved in multi-mode spontaneous parametric down-conversion in the regime of\nhigh gain. A stochastic model has been solved numerically to obtain\nquantitative results beyond the stationary plane-wave pump approximation. The\npulsed shape of the pump beam and other features of the system, such as spatial\nwalk-off and diffraction are taken into account. Their effect on the spatial\nquantum correlations predicted by the plane-wave pump theory is investigated,\nboth for near field and far field measurements, in a type I and in a type II\nphase-matching configuration.",
