Nonlinear Optical Effects in Polymer Dispersed Liquid Crystals Infrared (IR) nonlinear optical (NLO) crystals are the major materials to widen the output range of solid-state lasers to mid-infrared regions, but they are still inadequate for application due to.The nonlinear optical properties were studied using the Kurtz and Perry powder. Optical Properties of Polymer Dispersed Liquid Crystals Synthesis, growth and characterization of a nonlinear optical crystal. ) single crystals were grown by slow evaporation method using doped 1 L-Leucine.A general presentation of the optical properties is given and the observations of several nonlinear optical effects are reported. The last part of the book deals with more recent results on new composite materials: Polymer Dispersed Liquid Crystals (PDLC). The presentation is self-consistent and tutorial although the subject matter is of current research interest. The basic concepts of director optical reorientation and thermal nonlinearities are presented showing the fundamental theoretical approaches and describing the main experimental observations. The requisite of noncentrosymmetry for SHG has been successfully designed in various organic systems using a number of strategies. This monograph is devoted to a detailed treatment of the nonlinear optical properties of liquid crystals. Compared to inorganic crystal material, organic NLO materials exhibit high optical nonlinear and electro optic co-efficient, low dielectric dispersion, ultrafast response time and highly tailorable structure.
