Observation of mutual trapping and dragging of two-dimensional spatial solitary waves in a quadratic medium
Rights accessRestricted access - publisher's policy
We report experimental evidence for trapping of two-dimensional (2 + 1) spatial solitary waves in a KTP crystal resulting from its second-order nonlinearity. In addition, dragging of the solitary beams is observed as a function of fundamental input intensity and of the relative phase difference between the fundamental and the second harmonic when beams at both frequencies are coherently launched.
