Paper Abstract

We have developed a fiber laser system capable of producing over 100W of average power. We have achieved 1.5mJ/pulse/fiber resulting in peak powers in excess of 2MW with 0.6ns pulses and near diffraction limited beams. In another fiber, we have achieved over 0.5mJ/pulse with pulses of 700ps exceeding 500kW of peak power in polarization maintaining Ytterbium doped fiber. In both cases, wall-plug efficiencies, excluding cooling of the pump diode lasers, in excess of 15% were also achieved. The system we have developed is based in an all fiber design except for the last high peak power isolator requiring free space optics. With the advent of such a component, a scalable 1.5MW/arm all fiber laser system is proven to be possible.
