摘要

Time-resolved Z-scan measurements were performed in a Nd~(3+)-doped Sr_(0.61)Ba_(0.39)Nb_2O_6 laser crystal through ferroelectric phase transition. Both the differences in electronic polarizability (△α_p) and cross section (△σ) of the neodymium ions have been found to be strongly modified in the surroundings of the transition temperature. This observed unusual behavior is concluded to be caused by the remarkable influence that the structural changes associated to the ferro-to-paraelectric phase transition has on the 4f→5d transition probabilities. The maximum polarizability change value △α_p= 1.2 × 10~(-25) cm~3 obtained at room temperature is the largest ever measured for a Nd~(3+)-doped transparent material.
