Abstract

Symmetric bichromatic pumping in stimulated Raman scattering is predicted to lead to the generation of a multifrequency beam consisting of nearly 50 Raman lines of comparable amplitude. Such a beam may have application in laser fusion. We show that ultrabroad bandwidth may be generated in a time much less than the dephasing time of the nonlinear medium and that two distinct regimes of multifrequency generation exist – the coherent and incoherent regimes. In the coherent regime we have discovered that a large number of long-lived soliton pulse trains are spontaneously generated at the distinct Raman frequencies.
