Frequency Generation and Solitonic Decay in ThreeWave Interactions
Résumé
We consider experimentally three-wave resonant nonlinear interactions of fields propagating in nonlinear media. We investigate the spatial dynamics of two diffractionless beams at frequency ω 1 , ω 2 which mix to generate a field at the sum frequency ω 3. If the generated field at ω 3 can sustain a soliton, it decays into solitons at ω 1 , ω 2. We report the experimental evidence of the transition from steady frequency wave generation to solitonic decay in nonlinear optics.
