Nematic liquid crystals are the preferred materials for linear and nonlinear optics,
where frequently required photosensitivity is provided by appropriate doping. This
investigationis concerned with the determination of the Kerr constant of nematic
liquid crystal (9CHBT). The temperature dependence of the Kerr constant B for
azo dye doped nematic liquid crystalshas been studied. The sample has a positive
Kerr constant which increases with decreasing of temperature. The linear dependence
of the Kerr constant on (T – T)1is found to be ingood agreement with the
predications of the Landau-de Gennes model.
