Photoinduced effects in thin films of Te20As30Se50 glass with nonlinear characterization

Résumé

We discuss the influence of photoinduced effects (PIEs) on the measurements of nonlinear refractive indices and nonlinear absorption coefficients. A chalcogenide glass film Te20As30Se50 was studied using picosecond laser pulses at 1064 nm. The nonlinear imaging technique with phase object (NIT-PO) and the Z-scan technique were applied and their results are compared. The NIT-PO technique reveals clearly the influence of PIE on the samples' response, while by using the Z-scan technique we measured the deepness of ablated regions (holes) produced during the measurements.
