Velocity-locked solitary waves in quadratic media
arXiv:1003.3106 · doi:10.1103/PhysRevLett.104.113902
Abstract
We demonstrate experimentally the existence of three-wave resonant interaction solitary triplets in quadratic media. Stable velocity-locked bright-dark-bright spatial solitary triplets, determined by the balance between the energy exchange rates and the velocity mismatch between the interacting waves, are excited in a KTP crystal.
