Rusinov A.P., Kucherenko M.G., Fedorov D.S. HOLOGRAPHIC RECORDING OF THE RELIEF-PHASE GRATINGS IN POLYMERIC MEDIA BY THE LASER SWELLING MECHANISMThe process of laser initiation of relief structures on the films surface of polyvinyl alcohol (PVA) by the laser swelling mechanism. Laser action was selected in which ablation of the polymer excluded. The simple mathematical model of the recording of the relief-phase gratings by the laser swelling mechanism was proposed and the calculations which made on the basis of a theoretical model were compared to experimental data.Key words: laser swelling, relief-phase grating, diffractive efficiency, viscoelasticity.
