Abstract In this paper we have experimentally studied the CSE polarization dependence of dynamic transmission polarization holographic gratings (HG) recorded in azobenzene molecular glassy films W-75. A strong effect of recording and enhancing light polarizations on CSE is found. The highest CSE factor (showing the DE increase with respect to the initial DE ) of 14.5 was achieved in the case of recording and enhancing the HG by circular L-polarizations of light.
