We investigate the shapes, phases and weights of the found Schmidt modes for the generated parametric down conversion light in dependence on the separation of crystals and pump characteristics. The comparison between the calculated mode content and conventional Laguerre-Gauusian modes obtained from one crystal scheme is made.For high distances between crystals analytical expressions of the found Schmidt modes are found. Correlations of photons in the near field and far-field regions are analyzed. Methods to provide a selective amplification of a certain individual Schmidt mode based on the seeding by conventional Laguerre-Gauusian mode with rather simple spatial structure are suggested.
