Self-focusing of optical beams
WebJun 12, 2006 · We investigate the self-focusing dynamics of super-Gaussian optical beams in a Kerr medium. We find that up to several times the critical power for self-focusing, super-Gaussian beams evolve towards a Townes profile. At higher powers the super-Gaussian beams form rings which break into filaments as a result of noise. Our results are … WebWe 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.

WebTransverse optical intensity redistribution phenomena like self-focusing, self-defocusing and ring generation happen when a Gaussian laser beam is focused onto a nonlinear medium. We introduce a method for the evaluation of the diffraction pattern that is very simple, quick and suitable for computer implementation.
