Optical Properties of doped polymers

Poly vinyl alcohol (PVA) has been used in many applications since its discovery in 1924. PVA is a crystalline polymer, highly soluble in water, its dissolution requires the breaking of the crystal structure and need to be carried out at elevated temperature . One of the crucial features of the PVA consists in an existence of the promising acoustooptical effects determined by interaction of electron and phonon subsystems.
