Abstract
Experimental results of the transmission to total-internal reflection switching of a step-on CO2 laser beam by a dielectric-clad, isotropic liquid crystal film is presented. The use of the isotropic phase allows for polarization independence of the processes, while maintaining a moderate thermal nonlinearity. Dependence of switching speed on incident angle and energy density is evaluated. Experimental observations of the nonlinear switching effect with microsecond CO2 laser pulses are also presented.
