PbO–GeO2 rare earth doped glasses with silver nanoparticles as materials for IR laser triggers

Abstract

We have shown the possibility of operation by the piezooptical response of PbO-GeO 2 glasses doped with rare earth ions and silver nanoparticles by illumination of double frequency CO 2 nanosecond laser. Substantial influence of thermoannealing on the output photoinduced elastooptical susceptibilities was established. The effect is very sensitive to temperature and to the corresponding tensor components. The effect of thermoannealing leads to enhanced long-range ordering with the occurrence of corresponding trapping levels within the forbidden gaps. The discovered effects may be used for creation of low-temperature IR laser triggers.

Photoinduced piezooptics effect in TeO2–Ga2O3 glasses

“…We have performed the calculations for all the principal structural fragments presented in the The obtained by us parameters are better than the values of the photoinduced piezooptics obtained in the other glasses [25][26][27][28]. However, following their structure they are alsa promising for the incorporation of the rare earths favoring excellent fluorescence and photoinduced properties [29][30].…”
