We propose a new approach to the analysis of stochastic processes (such as fluctuating laser fields) with super-Gaussian statistics: the expansion of stochastic processes in terms of first and higher powers of Gaussian components, which are used like a basis set. This approach is applied to treat the super-Gaussian correlation effects observed in coherent anti-Stokes Raman scattering experiments using frequency-doubled pump laser fields. Our results give much better agreement with experimental data than previous theories do.

  11. If needed, one may add an independent zeroth-order term G0 to account for sub-Gaussian statistics. In some application this G0 term may be a coherent field [J. H. Churnside, Opt. Commun. 51, 207 (1984)]. [CrossRef]
