The concentration dependence of the fluorescence quantum efficiency in Nd3+ doped lead lanthanum zirconate titanate (PLZT), transparent ceramics, is presented. The total emission decay of the emitting level 4F3/2 is close to exponential, even for high Nd3+ concentration Nt, due to the very low probability of the cross relaxation energy transfer processes among ions. Owing to this low probability, it was inferred that Nd:PLZT presents lower concentration quenching than other laser materials as Nd:YAG. The figure of merit ηNt, where η is the fluorescence quantum efficiency, presents a maximum around 6.0 wt % Nd2O3, indicating the good prospects of concentrated samples for miniaturization of the laser medium (microchip laser).
