    Nth-order multifrequency coherence functions: A functional path integral approach. II.
    Rose, C. M.; Besieris, Ioannis M. (AIP Publishing, 1980-08-01)
    Nth_order multifrequency coherence functions arising in beam propagation through focusing media with random_axis misalignments and focusing media with additive statistical fluctuations are computed. The analysis is carried out by means of a simple formula which yields exact algorithmic solutions to a class of canonical path integrals.

    Nth-order multifrequency coherence functions: functional path integral approach
    Rose, C. M.; Besieris, Ioannis M. (AIP Publishing, 1979-07-01)
    A functional (or path) integral applicable to a broad class of randomly perturbed media is constructed for the nth_order multifrequency coherence function (a quantity intimately linked to nth_order pulse statistics). This path integral is subsequently carried out explicitly in the case of a nondispersive, deterministically homogeneous medium, with a simplified (quadratic) Kolmogorov spectrum, and a series of new results are derived. Special cases dealing with the two_frequency mutual coherence function for plane and beam pulsed waves are considered, and comparisons are made with previously reported findings.
