Paper Abstract
Novel configuration of combined Er/Er-Yb fiber amplifier is proposed to join advantages of both approaches (high gain and high efficiency). Co-propagating pump at 976 nm and signal at 1556 nm were coupled into a short piece of Er-doped fiber, where signal was amplified to a few Watts level. Then signal together with unabsorbed pump passed to LMA Er- Yb fiber. In this configuration, 2 ns pulses were amplified to 20 W of average power and 37 kW of peak power (limited by four-wave mixing). Differential efficiency reaches 37%, which is a record for fiber lasers with this peak power level.
