Abstract

The first higher power 3.5 μm pumping technique. Initial rapid power scaling has stagnated with no higher average power results in recent years. Power levels in excess of 10 W are necessary to unlock industrial and defense applications. Utilizing our rate equation based numerical model we investigate the expected performance of 3.5 μm fiber lasers configurations operating on the 10 W-20 W range. Fiber geometries and pump configurations are investigated. We also compare resonator with the simulated performance of master-oscillator power amplifiers configuration as a potential alternative for power scaling.
