Abstract

We measured the concentration of ${Nd}^{3 +}$ in ${PbWO}_{4}$ crystal by inductively coupled plasma–atomic emission spectrometry and determined the segregation coefficient to be 0.688. The polarized absorption spectra, polarized fluorescence spectra, and fluorescence decay curves of both the as-grown and the annealed ${Nd}^{3 +} : {PbWO}_{4}$ crystals were measured at room temperature. The effect of the annealing treatment on the spectroscopic properties of ${Nd}^{3 +} : {PbWO}_{4}$ crystal was discussed. The experimental results show that the annealing treatment is an effective method for improvement of the spectroscopic and laser performances of ${Nd}^{3 +} : {PbWO}_{4}$ crystal.
