Title

TMI investigations of very low NA Yb-doped fibers and scaling to extreme stable 4.4 kW single-mode output

Abstract
We present our recent results of scaling low-NA fibers to high average power by overcoming the TMI-limitations. We obtained a record output power of 4.4kW with a higher stability and smaller bending compared to our previous result.
