Abstract: The effect of trans-cis photoisomerisation of azofragments of a polymer film on the molecular reorientation of a liquid crystal is studied. It is shown that, using nanosecond laser pulses, one can perform both the reversible and static data recording in liquid-crystal cells with an azo-modified surface. The rise time of the reorientation is measured by the methods of dynamic holography to be about ~30 μs, and the grating efficiency achieves 15%.
