    The observation of an extraordinarily large purely optically induced refractive index change mechanism in methyl-red dye-doped nematic liquid crystal film is reported. A refractive index change coefficient of over 6 cm2/W was obtained. Visually observable self-diffraction and holographic grating diffraction can be generated with optical intensity as low as 40 μW/cm2. The response times are measured to be in the milliseconds regime.
