Description/Abstract

The unique combination of an active medium, nonlinearity, and negative group velocity dispersion make erbium doped fibers extremely attractive as the basic component of fiber soliton lasers. Recently, we have obtained greatly improved performance in a 1.06-µm pumped fiber amplifier based on Yb3+-sensitized Er3+ doped silica fiber. This development enables the use of readily available high-power solid-state mini-YAG lasers as pump sources and thus considerably scales up the output available from practical fiber lasers. Even more interestingly, the 1-W diode-pumped Nd3+-doped fiber laser recently developed in our laboratories can also be employed as a pump source in an all-fiber tandem-pumping arrangement. We report here a simple, inexpensive high-power fiber laser source based on the new codoped fiber, which is capable of generating transform-limited picosecond pulses with peak powers as high as 200 W.
