91. Effects of polarization on light propagation in laser-induced lens in guest host liquid crystals, T. Morisaki and H. Ono, J. Appl. Phys. 95 (2004) 3279-3284.


Focal length of a laser-induced lens in guest-host liquid crystals (GHLCs) was varied over a wide range by using both large optical nonlinearity and anisotropic complex refractive indices in GHLCs. The characteristics of the laser-induced lens were strongly dependent on the polarization state of the probe beam because the sign of the refractive index change was negative for extraordinary wave, while positive for ordinary one. These characteristics were well explained by theoretical calculating both the optical and thermal properties of the GHLCs
