In this work, Judd-Ofelt analysis is applied to rare-earth-doped lead-indium-phosphate glasses (RE-PbInPO{sub 4}, where RE = Er{sup 3+} and Nd{sup 3+}) in order to evaluate their potential as both glass laser systems and amplifier materials. The phenomenological Judd-Ofelt parameters {Omega}{sub (2)}, {Omega}{sub (4)}, and {Omega}{sub (6)} are determined for both rare-earth ions together with their quality factors and compared with the equivalent parameters for several other host glasses. The spontaneous emission probabilities and the lifetimes of the Nd{sup 3+} {sup 4}F{sub 3/2} laser transitions are determined and analyzed as a function of the optical quality factor. For Nd{sup 3+}-PbInPO{sub 4}, glass fluorescence emission (890, 1058, and 1330 nm) lines are observed. Highly efficient infrared-to-visible frequency up-conversion at 530, 550, and 670 nm as well as an intense infrared fluorescence emission ({approx}1540 nm) is observed in Er{sup 3+}-doped PbIn(PO{sub 4}) glasses pumped using 800 nm radiation excitation.
