摘要

Second order nonlinearity in polymer dispersed liquid crystal structures containing La₂CaB₁₀O₁₉ nanocrystals were measured with use of the Maker fringes method. The composites with different concentration of La₂CaB₁₀O₁₉ crystallites or without them were compared. It was shown that there is a strong influence of the crystals concentration on the second harmonic generation in such structures which can be additionally modified by external electric field.
