Radiative and nonradiative energy transfer from optically excited Ce/sup 3 +/ to Nd/sup 3 +/ has been studied in silicate laser glass. The quantum efficiency for nonradiative Ce/sup 3 +/..-->..Nd/sup 3 +/ transfer was determined from the Ce/sup 3 +/ fluorescence decay rates. The Ce/sup 3 +/ fluorescence decayed exponentially with a rate proportional to the Nd/sup 3 +/ concentration. Physical processes to account for the observed energy transfer are discussed. In addition, the utility of Ce/sup 3 +/..-->..Nd/sup 3 +/ energy transfer is considered for laser applications. In this context, the energy deposited in a Ce/sup 3 +/-Nd/sup 3 +/--codoped glass was calculated using a computer program containing a model of the xenon flashlamp spectrum as a function of current density. The results indicate that improvements in the optical pumping efficiency in typical Nd lasers are limited to <40%. (AIP)
