Laser spectroscopy of Nd3+ ions in GeO2-PbO-Bi2O3 glasses

The optical properties of Nd3+ ions in six different compositions of glasses based on GeO2, PbO, and Bi2O3 have been investigated by using steady-state and time-resolved laser spectroscopy. Judd-Ofelt parameters were derived from the absorption spectra and used to calculate the 4F3/2→4H11/2 stimulat...
