An experimental study of the interactions of self-trapped white light beams in a photopolymer

Abstract

Interactions of two parallel-propagating and mutually incoherent white light beams were examined in a photopolymerizable organosiloxane. The beams fused when separated by a distance corresponding to the width of each beam but at separation distances⪢beam width, formed two self-trapped beams that repelled each other. At separation distances<beam width, they suffered filamentation but ultimately fused into a single self-trapped beam.
