O. Haderka et al., GLOBAL CHARACTERISTICS OF THE DYNAMICS OF DEGENERATE PARAMETRIC NONLINEAR PROCESSES, Quantum and semiclassical optics, 8(6), 1996, pp. 1159-1167
A new method for characterization of the long-time dynamics of generat
ion of second and higher harmonics and subharmonics is presented. This
method is based on calculation of the spectra of moments of photon nu
mbers and enables us to predict the global behaviour of the process. T
his is demonstrated by numerical results, which are discussed and rela
ted to the time-domain dynamics and to short-time analytical results.
