After illumination by single-beam polarized pulse laser (532 nm) with energies below the ablation threshold energy, periodic microstructure was prepared on an azobenzene-containing poly(urethane-imide) (PUI) film surface. The reflective polarized IR results proved that the azobenzene group tended to
