摘要：

Room-temperature measurements of laser emission cross sections of Nd3+ ion in sodium-beta" alumina at 1.06 and 1.35-mu-m as well as the fluorescence branching ratios of 4F3/2 to 4I(j) manifolds are reported. A theoretical calculation based on absolute absorption measurements when a modified Judd-Ofelt phenomenological intensity analysis was used is reported. The cross sections thus determined are sigma-1.06 = 3.1 +/- 0.3 x 10(-20) cm2 and sigma-1.35 = 0.6 +/- 0.1 x 10(-20) cm2, respectively. The emission cross section at 1.06-mu-m was also determined by small-signal-gain measurements and was found to be in good agreement with the above value.
