On the kinetics of nonradiative energy transfer in Yb — Er phosphate glasses excited by a diode laser

The luminescence of a Yb - Er phosphate glass excited by a diode laser is studied as a function of the density of energy absorbed by a sample and the pump radiation intensity. An abrupt change in the depopulation rate of the Yb{sup 3+}({sup 2}F{sub 5/2}) level was observed after switching off the pu...

Zusammenfassung:The luminescence of a Yb - Er phosphate glass excited by a diode laser is studied as a function of the density of energy absorbed by a sample and the pump radiation intensity. An abrupt change in the depopulation rate of the Yb{sup 3+}({sup 2}F{sub 5/2}) level was observed after switching off the pump laser. This effect is explained qualitatively based on the kinetics of nonradiative energy transfer in glasses and crystals.
