摘要: Abstract A new type of asymmetry the spontaneous Raman scattering (ASRS) is considered for multilayered crystals ∈-GaSe (D 6 3h -symmetry) where not only probabilities light are different to right and left directions but also phonon frequencies half-widths differ. ASRS has been discovered Si-crystals (O 7 h ) after UV irradiation also. We showed that interface modes, chaotic behavior nonlinear dynamical systems Duffing potential renormalization driven by noise can describe explain peculiarities give rise in crystals. An represents conveniently clearly experimental physical model study chaos optics.
