A new reduced mode overlap (RMO) single mode fiber design is proposed and demonstrated. For the first time saturated photo darkening operation is observed in a nominal 350 W Yb / Al co-doped silica fiber laser. After 1500 hours operation less than 7% slope efficiency degradation is found and further 500 hours operation show no degradation.
