Abstract

To understand the dynamics and correlations between photodarkening (PD) and photoinduced volume changes (PVC) in chalcogenide glasses, we built up a in-situ simultaneous PD and PVC measuring system based on computer analyzed spectroscope and phase-shifting interferometer (PSI). This new system provides us the records of both PD and PVC during illumination with common time axis. We have found that significant transient components of PD and PVC exist only during illumination. It is also found that the PVC reaches equilibrium faster than the PD..
