The Influence of the Finite Size of the Light Spot on the Laser Induced Reorientation of Liquid Crystals
The threshold intensity for the laser induced deformation of nematic liquid crystals is calculated as a function of the spot size of the illuminating beam. It is shown, that due to the small size of the light ...

Chapter
Reorientation of Liquid Crystals by Superposed Optical and Quasistatic Electric Fields
The electric field of a CW laser beam can reorient a nematic liquid crystal. Experiments on the influence of a superposed quasistatic electric field are reported showing that this can reinforce or weaken the l...

Chapter
The effect of an optical field on the nematic phase of the liquid crystal OCBP
We have observed a complex structure and an extraordinarily large divergence (30–40°) of an argon-laser beam emerging from an OCBP crystal placed at a focal constriction. The experimental results can be explai...

Undamped oscillations of NLC director in the field of an ordinary light wave
We have investigated experimentally some characteristic features of orientational aberration self-focusing of an ordinary light wave in a homotropically oriented NLC. A qualitative explanation of these feature...
