Agranovich We analyse triangular spectra that appear in many branches of physics that deal with parametricallydriven systems, and give a simple theoretical analysis for them in terms of the nonlinear dynamics of multimode fields. Such spectra appear universally as a result of an exponential decay of the nonlinearly generated frequency modes of many parametrically-driven… CONTINUE READING
