The spectroscopic properties of trivalent dysprosium (Dy^{3+}) doped LiNbO_{3} crystals have been investigated at various temperatures. Absorption, emission, excitation and lifetime measurements have been performed and discussed in the framework of Judd-Ofelt approach. The stimulated emission cross sections of the strongest transitions of Dy ^{3+} ion have been estimated. A stimulated emission has...
Lifetime of the main fluorescence level, ^{4}S_{3/2}, of erbium pentaphosphate monocrystal was measured to be 380±20 ns. Direct excitation to higher energy levels, and also indirect excitation with the use of an infrared beam were applied.
