Abstract

Four-wave mixing in nematic liquid crystals differs from that in a different medium, such as atomic vapors or isotropic materials. In a nematic liquid crystals (NLC), wave mixing is due to spatial holograms constructed by the four interacting waves. Using the holographic approach, the authors have recorded diffractive index gratings in the NLCs. A theoretical study of nonlinear optical effects in NLCs, including degenerate four-wave mixing, is presented. Also presented are a description of the degenerate four-wave mixing optical geometry used and results obtained from the reconstruction of images.
