Abstract: | The spectral evolution of an intense electromagnetic pulse in the course of a coherent twophoton Raman interaction with a medium is analyzed under conditions such that the approximation of slow envelopes is not valid for the field or polarization of the medium. There exist threshold power levels at which a pronounced self-roadening of the field spectrum occurs if the field spectrum includes the frequencies ft, where •fiCl=E2—El is the energy difference between the levels involved in the stimulated Raman scattering. The results found here agree with experimental data on the generation of a supercontinuum in various media. In particular, there is agreement in terms of the spectral self-transformation of optical solitons in optical fibers. |
