Abstract
In this paper, we show theoretically that a cholesteric liquid crystal exhibits a retro-self-focusing effect and a pinholing effect under the Gaussian intensity distribution of an incident optical field. The retro-self-focusing effect is a result of pitch dilation due to intense optical radiation. We confirm these theoretical predictions by experiment.Keywords
