Effect of the background absorption in achieving a radiation-balanced ZBLAN fiber laser (Conference Presentation)

Paper Abstract

The modal instability due to heating has been a limiting factor in the ongoing progress towards power scaling in fiber lasers and amplifiers. Radiation balancing has been suggested as a feasible approach for heat mitigation, for which Yb-doped ZBLAN is a recommended gain medium. In this study, we introduce a non-destructive and non-contact method to characterize Yb-doped ZBLAN fibers and show that it is suitable for designing a radiation-balanced fiber laser. Numerical simulations based on measured values indicate that background absorption is the main hindrance to be overcome in such designs.
