Resumo
An analytical investigation of the refractive index
behavior of an ytterbium-doped optical fiber silica glass as a
function of the core-clad temperature, upper-level population
laser density, and pumping signal intensity is presented in
this paper. For the substantiation of the investigation, three
fundamental expressions were used, which describe the changes
in the refractive index due to these physical phenomena in
the laser medium. The model was evaluated considering a 500
W steady state fiber laser, operating in a two-end pumped
configuration.
