Abstract
Nd 3+ -doped Y 2-2 x La 2 x O 3 ( x =0.08) transparent ceramics were fabricated by conventional fabrication process. Spectroscopic properties of the samples were investigated. The absorption band of Nd 3+ : Y 1.84 La 0.16 O 3 was broad covering the wavelength range 780—850 nm. When doped with 1.5at% Nd 3+ , the cross sections of the sample at 820 nm and laser diode pumped 808 nm were 1.81×10 -20 cm 2 and 1.54×10 -20 cm 2 , respectively. The strongest emission peak of the sample was centered at 1078 nm with long fluorescent lifetime, broad emission bandwidth and high quantum efficiency. Because of the additive La 2 O 3 , the spectroscopic quality parameter ( X Nd ) of matrix was decreased from 1.6 to 0.46, thus the fluorescence branch ratio of 4 F 3/2 — 4 I 11/2 transition was increased to 56.82%. These properties of Nd 3+ : Y 1.84 La 0.16 O 3 transparent ceramic are benefitial to achieve high efficient laser output and ultrashort modelocked pulse.
