Abstract

Thin polymer film doped with optical chromophore porphyrin are shown to respond to irradiation with laser light (λ=405 nm). By simultaneous scanning with laser beam and continual mechanical movement of the polymer film regular grating pattern is formed on the polymer surface. Parameters of the grating vary in wide range as a function of the movement velocity and the laser intensity. Submicron, periodically structures can be prepared using the proposed technique.
