Polarized-light optical actuation in chalcogenide glasses - macroscopic model

摘要

The microscopic and macroscopic models of photoinduced anisotropy in general and photoinduced optomechanical effect in particular are critically reviewed. Based on current experimental data available a revised macroscopic model of photo-induced anisotropy is given. As opposed to expansion and contraction phenomena considered previously, the photoinduced polarization dependent viscosity change is proposed to explain the experimental data of the optical actuation in chalcogenide glasses.
