摘要：

Two mechanisms of optical response in liquid crystals (LC) of homologous series 4-n-butyl-4'-n-alkoxyazobenzenes (BAAB), namely the photochemical phase transition and reorientation in bulk of LC are considered. The temporal parameters of writing (Art laser) and erasing (He-Ne laser) of information on BAAB on the basis of photoinduced phase transition are presented. The phenomenon of reorientation of BAAB molecules in planar oriented layer induced with second of Nd:YAG laser in directions orthogonal to initial alignment was revealed.
