Abstract

Spectroscopic properties of neodymium-doped yttrium orthovanadate crystals were measured in the temperature range between 5 and 350 K . Crystals fabricated by different suppliers, with 0.3 and 1 at % Nd 3 + , were compared. For each temperature, the stimulated emission cross sections of the Nd 3 + F 3 2 4 decay to the I 9 2 4 , I 11 2 4 , and I 13 2 4 states were obtained using the Fuchtbauer–Ladenburg and the reciprocity techniques. Nd : Y V O 4 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 Nd 3 + F 3 2 4 excited-state lifetime is discussed and an explanation is suggested.
