    "abstract": "We investigate the nonlinear interaction between two laser beams in a plasma\nin the weakly nonlinear and relativistic regime. The evolution of the laser\nbeams is governed by two nonlinear Schroedinger equations that are coupled with\nthe slow plasma density response. We study the growth rates of the Raman\nforward and backward scattering instabilities as well of the Brillouin and\nself-focusing/modulational instabilities. The nonlinear evolution of the\ninstabilities is investigated by means of direct simulations of the\ntime-dependent system of nonlinear equations.",
