利用Judd-Ofelt （J-O）理论对晶体场诱导电偶极子跃迁的光谱强度进行系统研究表明，通过适当选择玻璃成分，可以为特定的激光应用量身定制掺钕玻璃。随玻璃成分的变化，报告了以下性质：诱导发射截面、峰值荧光波长、有效荧光带宽、辐射寿命、跃迁概率和荧光分支比。改变了玻璃成网剂和网络改性剂离子。在这些研究中，Nd3+， 4f_{3/2} \右列4i_{11/2}激光跃迁的诱导发射截面通过改变玻璃主体而变化了4倍以上。
Systematic studies of spectral intensities using the Judd-Ofelt (J-O) theory for crystal-field-induced electric-dipole transitions demonstrate that Nd-doped glasses can be tailored for specific laser applications by proper selection of the glass constituents. Variations with glass composition are reported for the following properties: induced-emission cross section, peak fluorescence wavelength, effective fluorescence bandwidth, radiative lifetime, transition probabilities, and fluorescence branching ratios. Both glass network formers and network-modifier ions were changed. In these studies the induced-emission cross section for the Nd3+,4 F_{3/2} \rightarrow 4 I_{11/2} laser transition was varied by more than a factor of 4 by changing the glass host.
