Abstract

Spontaneous solitons in stimulated Raman scattering (SRS) were first demonstrated in CO₂-laser pumped para-H₂¹ and subsequently also in frequency doubled Nd:YAG-laser pumped para-H₂.^2-4 The origin of such spontaneous solitons is the rapid phase variation of the Stokes field which occur at a noisy level. It creates a phase mismatch of π between pump and Stokes field. Gain and loss conditions are thus reversed. This causes the soliton excitation.^1,2
