In an underdense plasma, stimulated Raman scattering (SRS) and stimulated Brillouin Scattering (SBS) are two laser parametric instabilities of a greatest relevance. We show examples of isolated nonlinear SRS and SBS and discuss some of the experimental SRS anomalies that largely depart from the standard theory. As an example of a complex interplay between nonlinear SRS and SBS we show results of their anticorrelated behavior. Based on a concept of self-organization we put forward a simple model of SRS capable of reproducing basic experimentally observed anomalous features. Finally, we close with an example of fascinating new physics observed in SRS induced by an ultra-short pulse relativistic-intensity laser.}, title = {Complexity in Laser Plasma Instabilities}, year = {1999} }
