Abstract
Results of mathematical modeling and experimental investigation of spontaneous soliton generation in forward stimulated Raman scattering (SRS) are reported. The duration of measured soliton pulses varied from 15 to 30 ps corresponding to the relaxation time T2 in compressed methane. The peculiarities of Raman solitons generation under essentially different quasi-steady-state and transient regime of SRS excitation were observed. For pump pulses with duration of 300 ps and Gaussian beam profile the probability of soliton-like pulse observation was only about 0.0034. For longer pump pulses and for pulses with top-hat beam profile that probability was considerably higher. The influence of mutual diffractive focusing of laser and Stokes beams on the process of Raman solitons generation was experimentally confirmed.
