title: Quadratic solitary waves in a counterpropagating quasi-phase-matched configuration.
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 beams and estimate the power level required for their observation.
