Abstract
Spectroscopic properties of neodymium-doped yttrium orthovanadate crystals were measured in the temperature range between 5 and . Crystals fabricated by different suppliers, with 0.3 and , were compared. For each temperature, the stimulated emission cross sections of the decay to the , , and states were obtained using the Fuchtbauer–Ladenburg and the reciprocity techniques. shows higher absorption at room temperature and higher stimulated emission cross section with similar variation with temperature when compared with Nd:YAG. The anomalous dependence on temperature of the excited-state lifetime is discussed and an explanation is suggested.
