Paper Abstract

We propose a simple exactly solvable kinetic model of transcis processes accompanying build-up of diffraction gratings in a polymer matrix doped with azobenzene chromophores, illuminated with spatially modulated and linearly polarized light in degenerate two-wave mixing experiments. This model mimics the essential features of a more realistic kinetic model studied recently using Monte Carlo simulations. A qualitative agreement between an experiment, Monte Carlo simulations and simple kinetic modelling implies that basic photoisomerisation processes during diffraction grating recording are of relatively simple nature. In particular, two exponential dependence of diffraction efficiency versus time measured in experiments and found in Monte Carlo simulations is easily described by the model.
