Abstract
Fiber lasers have the potential for cost reduction in amplifiers for DWDM applications. This is achieved through efficient use of broad-area lasers. Yb fiber lasers operating at or near the gain peak of 978nm are of particular interest. Lasing on this transition can be realized through either a tapered multi-mode oscillator or a strictly designed double-clad fiber. This work will be reviewed and compared to alternative power scaling techniques.
