Abstract: 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 omega(1), omega(2) which mix to generate a field at the sum frequency omega(3). If the generated field at omega(3) can sustain a soliton, it decays into solitons at omega(1), omega(2). We report the experimental evidence of the transition from steady frequency wave generation to solitonic decay in nonlinear optics. (C) 2009 Optical Society of America
