Quadratic solitary waves in a counterpropagating quasi-phase-matched configuration
arXiv:patt-sol/9906002 · doi:10.1364/OL.24.000835
Abstract
We demonstrate the possibility of self-trapping of optical beams by use of quasi phase matching in a counterpropagating configuration in quadratic media. We also show the predominant stability of these spatial self-guided beams and estimate the power level required for their experimental observation.
