Optical Second Harmonic Generation in Various Liquid Crystalline Phasestals. The components of the cubic non-linear susceptibility tensor were measured for substances with different molecular structure. The phase-matched SHG was observed for all the compounds investigated. The directions of the phase synchronisms as well as the corresponding non-linear susceptibilities

The Influence of the Finite Size of the Light Spot on the Laser Induced Reorientation of Liquid Crysbeam. It is shown, that due to the small size of the light spot, the optical threshold is higher than that expected from the Fredericks threshold formula for static electric fields of infinite large dimension in the cell plane. Experimental data measured on a homeotrop OCB (octyl-cyano-byphenyl) sam

External field enhanced optical bistability in nematic liquid crystalsopic nematic liquid crystal. With a low external field applied transverse or parallel to the laser propagation direction, optical bistability can always be suppressed or enhanced and hence can be seen in all existing nematics at a low laser power (typically < 1 kW/cm.). The fields corresponding to t

Observation of optical field induced first-order electric Freedericksz transition and electric bista It is experimentally demonstrated that an applied optical field can transform the electric Freedericksz transition from second order to first order. The molecular reorientation as a function of electric field is then characterized by a hysteresis loop which exhibits the electric bistability. The re
