Analysis of the kinetics of diffraction efficiency during the holographic grating recording in azobenzene functionalized polymers

Various techniques and methodologies are used to observe the efficiency of the scattering of the light during the laser-assisted holographic grating recording process in films of several azobenzene functionalized polymers. The analysis of the temporal evolution of diffraction efficiency for the same grating formation kinetics suggests that proper and adequate care should be taken during the experiment to get accurate results.
