Abstract

Stimulated Raman scattering (SRS) of ultrashort pulses at saturation stage is investigated both theoretically and experimentally. A theory of light intensity self-limiting in Raman media concerning the peculiarities of Stokes wave amplitude-phase spatial transverse distribution is developed. Conversion modes classification based on nonstationary SRS theory, taking into account the parameters of coherent Stokes pulses formed from noise distribution at initial stage of SRS process, is represented. Stable polychromatic 10 ps pulses have been obtained in YAG:Nd³⁺ laser with intracavity Raman conversion in potassium gadolinium tungstate (PGT) crystal.
