Polarized and time-resolved resonant laser-excited fluorescence spectra were recorded for the /sup 4/F/sub 3/2/ ..-->.. /sup 4/I/sub 11/2/ transition of Nd/sup 3 +/ in several commercial silicate and phosphate glasses. Excitation sources were pulsed Nd:LiYF/sub 4/ (1053 nm) and Nd:Y/sub 3/Al/sub 5/O/sub 12/ (1064 nm) lasers. Measurements of line-narrowed spectra yield linewidths ranging from 35 to 64 +/- 10 cm/sup -1/, depolarization ratios from 0.81 to 0.93, and spectral energy transfer rates approx.< 3 x 10/sup 3/ s/sup -1/ for Nd/sup 3 +/ concentrations approx.< 2 x 10/sup 20/ cm/sup -3/. The variations of these properties with wavelength and glass composition are discussed. Hole burning and gain saturation of glass laser amplifiers due to spectral and polarization inhomogeneities can be predicted from these results.
