ABSTRACT:
A transparent, organic polymer substrate organized for optical frequency conversion is prepared by subjecting a material of a transparent, organic polymer which incorporates therein transparent, active organic molecules which have a second order, microscopic, optical nonlinearity to the simultaneous action of a first laser beam at fundamental frequency .omega. and a second laser beam of second harmonic frequency 2 .omega. for a time adequate to induce a second order, macroscopic nonlinearity in the transparent active organic molecules in the structure.
