Abstract
A laser-induced thermomechanical effect in twist-aligned nematic liquid crystals has been revealed and experimentally studied. It has been proved that the nature of this phenomenon is orientational rather than diffraction. It has been shown that the orientational optical nonlinearity resulting from this effect can be as strong as the well-known giant optical nonlinearity. Moreover, giant optical nonlinearity does not exist at normal incidence of the laser beam, whereas thermomechanical nonlinearity remains of the same order of magnitude at any angle of incidence of the beam.
