Abstract

We report what to our knowledge are the first observations of an increase in the On-Axis intensity of an intense cw On-Resonance beam resulting from nonlinear absorption and diffraction during its propagation through a highly absorbing medium (sodium vapor). This "Self-Focusing" is not a Self-Lensing; instead it is modeled well by placing an aperture part way through the cell: The stripping by the aperture approximates the effect of the nonlinear absorption, and then Fresnel diffraction results in On-Axis minima and maxima.
