Shtykov M.M., Blinov L. M., Dorozhkin A. M. , Barnik M. I.
The generation of the second optical harmonic has been investigated in the nematic and smectic phases of different liquid crystals for homeotropic and planar orientations of the samples. The generation of the second harmonic is interpreted within the framework of the multipole mechanism.
