- Very large core diameter with highest darkening-free pump absorption on the market allows shorter fiber length enabling compact, less costly designs and reduced non-linear effects
- Photodarkening-free performance at high power ensures stable long-term operation
- Wide, flat absorption from 910nm to 970nm reduces pump cooling / stabilization costs and allows 940-960nm pumping
