The properties of a light beam passed through an NLC layer with positive orientational nonlinearity and then reflected from the NLC–substrate interface have been experimentally studied. The divergence and the intensity profile of this beam were fou

Nonlinear-optical properties of nematic liquid crystal 5CB doped with a small amount of high-molecular polymer MEH-PPV (poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene]) have been studied. This liquid crystalline system was shown to exhib

Orienting influence of femtosecond laser pulses on nematic liquid crystals has been studied. We have shown experimentally that in both a nematic liquid crystal doped with anthraquinone dye D4 and nematic matrix “mixture A” (consisting of azoxymol

A new type of reversible orientation first-order transitions in a nematic liquid crystal (NLC) in the optical and low-frequency electric fields is studied experimentally and theoretically. It is shown that these transitions, characterised by a distin

We report on the observation and investigation of the light-induced director reorientation due to the change in the orienting properties of the boundary surfaces of the homeotropically aligned NLCs in the samples containing pure (nondoped) nematic ma

An interaction of the director of NLCs, doped with mono- and diazodyes and showing the sign-inversion nonlinearity, with the simultaneously applied light and low-frequency electric fields has been studied using the technique of the aberrational self-

The interaction of linearly and circularly polarized beams with a nematic liquid crystal doped with light-absorbing dyes has been studied by light-diffraction and microprojection methods. It has been found that there is a threshold for the emergence

The interaction of narrow light beam with homeotropic liquid crystal 8CB in the region of phase transition smectic-nematic has been investigated. It was found out that the action of light beam leads to nonplane distortion of the director field (appea

1. A memory effect was observed in a smectic liquid crystal without artificially increasing its absorption in a wide temperature interval — from the nematic-phase temperature (t ≤ 35°C) to room temperature (t ⋍ 21–22°C).

Experimental observations and theoretical calculations of the interaction of an ordinary light wave with a homeotropically aligned nematic liquid crystal (NLC) are presented. It was observed that by increasing the light power, aperiodic, damped, peri
