Temperature Effects on the Emission Properties of Yb-Doped Fiber (Postprint)

Abstract

Ytterbium-doped fiber lasers are making impressive leaps in power production. Yet in spite of fibers large surface area to volume ratio which is beneficial for cooling, such power inevitably leads to high core temperatures that in turn affect the laser performance. In this letter, the temperature effects on the emission and fluorescence lifetime of ytterbium doped optical fibers are investigated. From these the temperature dependent emission and absorption cross sections are calculated. A corresponding theoretical treatment presents the necessary conditions to eliminate radiation trapping.
