Title: E-band fiber laser performance and power analysis with longitudinally averaged population modeling

Abstract

To help facilitate the modeling of new fiber laser systems, such as those with complex functional microstructures, we report on a simplified modeling methodology that can accommodate the parasitic kinetic effects often present in such systems. The essence of our approach is to integrate kinetics over the length of the gain medium at the outset, thereby forfeiting longitudinally resolved information about the system but simplifying its energetics analysis. To illustrate the benefits of our new approach over more conventional coupled-rate-equation analyses, we apply our model to an Nd 3 + -doped fiber laser operating on the F 3 / 2 4 - I 4 13 / 2 transition at 1400 nm. The model produces closed-form solutions for the various output channels available to the pump power and enables projections of ultimate laser performance to be conveniently generated.
