  • Femtosecond and picosecond time resolved analysis of rotation of liquid crystals about their long axis

    • 摘要:

      Using an optical Kerr effect experiment, the rotation of a series of cyanobiphenyl liquid crystals about their long axis in SmA phase and their relaxation were measured for the first time on picosecond and femtosecond time scales. The fast observed optical nonlinearity is related to cyanobiphenyl head rotation and is bigger compared to benzene.
