## Abstract

The stimulated emission cross section $\sigma_p$ for the 1060 nm transition of $Nd^{3+}$ in lead borate and bismuth borate glasses has been determined from fluorescence measurements. The compositional dependence of $\sigma_p$ , which has been evaluated using radiative transition probability, refractive index of the host glass, effective fluorescence linewidth, and position of the band, with $PbO/Bi_2O_3$ content is investigated. The $\sigma_p$ values of the 1060 nm band of $Nd^{3+}$ for lead borate and bismuth borate glasses are found to be in the range $2.6-5.73 \times 10^{-20}cm^2$ at 298 K and $3.0-6.3 \times 10^{-20}cm^2$ at 4.2 K. The $\sigma_p$ values are comparatively large suggesting the possible utilization of these materials in laser applications.
