Abstract The optical transition probability of Nd3+ (0.5mol%) doped lanthanum-modified lead zirconate titanate (PLZT) is investigated. The absolute intensities of its forced electric dipole transitions between 400nm and 1000nm were measured, from which we obtain three phenomenological parameters, Ω2= 0.787×10-20cm2, Ω4= 1.182×10-20cm2, and Ω6=1.042×10-20cm-20, according to the Judd--Ofelt theory. The radiation lifetime (346.9μs) of the 4F3/2 metastable state, the stimulated emission cross-section σij= (2.49×10-21cm2, 6.51×10-21cm2, 2.17×10-21cm2), and the fluorescence branch ratios are calculated. We also measured the fluorescence lifetime (155.84μs) and calculated the quantum efficiency (46.1%). The analysis reveals that Nd103+-doped PLZT, based on its large electro-optical effect, has potential applications in active optical devices.
