Interference oscillations in the optical response of a hybrid-aligned nematic with a surface disclination line to a pulsed magnetic field

The propagation of light through a hybrid-aligned nematic layer with a surface disclination line is investigated in a pulsed magnetic field. The experimental dependences of light intensity I on time t accompanied by interference oscillations are presented. The shift and expansion of the interference extrema as functions of the magnetic field pulse length during the reaction are shown. The I ( t ) dependence for the relaxation process is calculated with allowance for scattering. The calculated I ( t ) dependence agrees well with the experimental dependence over the entire hybrid-aligned nematic layer, except for the surface layer.
