Abstract

We investigate the features of femtosecond laser pulses interaction with pure and dye-doped nematic liquid crystals. For femtosecond laser pulses interacting with dye-doped nematic liquid crystal we found the distinction between the efficiency of liquid crystal director reorientation in comparison to the continuous wave irradiation. The mechanisms responsible for such distinction associated with changes of intermolecular forces under two-photon absorption and light induced changes of anchoring conditions are discussed.
