Photoinduced gliding of the surface director in azo‐dye doped nematic liquid crystals

We report photoinduced surface director gliding with azo dye‐doped nematic liquid crystals. This gliding has the same characteristics as that induced by an applied magnetic field. Fast and slow dynamic regimes are observed, the latter fitting to a stretched exponential. In addition, the gliding demonstrates a ‘sensitizing’ effect for sequential measurements.
