Abstract
Excited state lifetimes, ground state absorption, excited state absorption, and stimulated emission cross sections govern the performance of luminescent sources and amplifiers. The role of host glass in determining the shape and magnitude of these quantities is outlined and useful relationships among cross sections are presented. Using the theory of McCumber it is possible to obtain the shape of a cross section spectrum from a measurement of the inverse process and to set limits on the noise figure of resonantly pumped amplifiers. A simple analysis can be used together with easily obtained information to identify glass compositions most promising as hosts for Nd3+ amplifiers at 1300 nm.
