摘要：
Photoinduced changes of transmittance and refractive index of 5CB nematic liquid crystal doped with anthraquinone dye under the action of femtosecond laser pulses are studied. The processes are considered in terms of strong interaction between liquid crystal matrix and dye molecules that is demonstrated by the example of fluorescence spectra.
