Undamped oscillations of NLC director in the field of an ordinary light waveWe 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 features is offered.

Introduction and crystalline-like features (macroscopic anisotropy). The substances showing this phenomenon are called ., the intermediate phases are termed . or .. By now thousands of liquid crystals are known and at least ten thermodynamically different mesophases are recognized.

Light Propagation in Anisotropic Stratified Media in the Quasi Adiabatic Limiton of the conventional 4x4 Berreman matrix. An approximate propagation equation is deduced for the Jones vector giving the polarization state of the wave propagating in the forward direction. The results obtained by using this equation are compared with the exact ones and the limits of validity of the present approach are discussed.

Pseudo-Stokes parameter representation of light propagation in layered inhomogeneous uniaxial media e parameters are linearly related to the familiar Stokes parameters and obey a simple first-order differential equation. Conservation of energy and angular momentum is preserved under this approximation.

The Orientational Mechanism of Nonlinearity and the Self-Focusing of He-Ne Laser Radiation in Nematied 60 .m thick NLC layer has been carried out experimentally. The measured value of the nonlinearity effective constant .. = 0.07 cm./erg corresponds to theoretical predictions, and turns out to be larger than the CS. nonlinearity by ≈ 10. times.

The Influence of the Finite Size of the Light Spot on the Laser Induced Reorientation of Liquid Crysula for static electric fields of infinite large dimension in the cell plane. Experimental data measured on a homeotrop OCB (octyl-cyano-byphenyl) sample fit well the theoretical curve. Results obtained on the temperature and wavelength dependence of the threshold can be interpreted on the basis of the given theory.

0923-1749 ery, although many significant results were found, liquid crystal research remained a marginal topic of condensed matter physics. The situation changed in the sixties. At that time the remarkable electro-optical properties of liquid crystals were recognized and found soon widespread application in n
