Photoinduced piezooptical changes caused by microsecond CO(2) Infrared lasers in lead-germanate rare earth tridoped glasses
Original language description
We have observed substantial influence of the illumination by 3.5 mu s CO(2) laser on the piezooptical coefficients of 59 PbO -41 GeO(2) (in wt.%) glasses prepared with Tm(2)O(3), Er(2)O(3), Yb(2)O(3) using the following concentrations (in wt.%): B-Tm(2)O(3) (0.5)/Yb(2)O(3) (1.0)/Er(2)O(3)(0.5); C-Tm(2)O(3)(0.5)/Yb(2)O(3)(1.0)/Er(2)O(3) O(1.0): D-Tm(2)O(3) (0.5)/Yb(2)O(3) (1.0)/Er(2)O(3) (2.0). We have found that the maximal changes were observed for B samples that contain the lowest concentration of Er(2)O(3). The maximal changes are observed around 360 nm near the fundamental absorption edge. There exists some correlation between the maximal intensities of the photoluminescence and the maximal piezooptical changes. The CO(2) lasers cause preliminaryphotothermal changes. The existence of the maxima may be caused by a competition between the phonon and anharmonic phonon subsystems, which are very sensitive to the temperature.
