| Popis: | 4ZnO · 3B 2 O 3 glasses doped with Nd 3+ and Er 3+ were investigated by optical spectroscopy. Emission transition probabilities, radiative life-times and fluorescence branching ratios for several excited states of the Nd 3+ and Er 3+ ions were estimated from the room temperature absorption spectra. The stimulated emission cross sections σ p for the near infrared laser transitions of Nd 3+ and Er 3+ were obtained from laser-excited luminescence spectra. The values of σ p are comparable with those shown by glasses used in solid state laser applications. |
