Abstract
Rare-earth doped fiber lasers are now considered suitable sources for the 1.0-, 1.5-, and even 2.0-μm regions in a relatively large number of applications. In particular, Yb3+-doped fiber lasers have received strong interest due to its high quantum efficiency, broad tunability, and available high output power. In this work, we present results on a newly developed code for the simulation of the critical power that is required when designing double-clad high-power Yb3+-doped fiber lasers, which are based on novel inner-clad structures. From our results, we can also estimate σep, σel, σap, and σal for the aforementioned free-running laser cavities. Finally, we will formulate our predictions for feasible fiber laser cross sections.
