Self-focusing and Self-Trapping of Optical Beams Upon Photopolymerization

Self-focusing and Self-Trapping of Optical Beams Upon Photopolymerization

A S Kewitsch et al. Opt Lett.

Abstract

We demonstrate theoretically and experimentally that optical beams are self-focused and self-trapped upon initiating photopolymerization. This unique nonlinear optical phenomenon is dependent on the optical exposure and produces permanent index-of-refraction changes larger than 0.04. The resulting nonlinear wave equation is shown to be nonlocal in time and displays self-trapped solutions only for sufficiently low average optical intensities.
