ON THE OPTIMUM CONDITIONS FOR THE SELF-ORGANIZATION IN 3-WAVE NONLINEAR COUPLING

Optimum conditions for the temporal compression of light pulses in thr ee-wave nonlinear optical processes (optical parametric interaction, s timulated Brillouin scattering) are investigated. The energies of pump pulses twice above the generation threshold are shown to be most favo rable for maximum temporal compression. This result is interpreted fro m a thermodynamical point of view: by considering the optical parametr ic oscillator as a system far from thermodynamical equilibrium, and by analyzing the efficiency of production of a qualitatively new and coh erent output by it.
