We report on a stretched-pulse additive-pulse mode-locked erbium-doped
fiber laser pumped by a master-oscillator/power-amplifier diode at 98
0 nm. This laser operates at 1.55 mu m and puts out as much as 90 mW o
f average power at 40 MHz with pulse widths that are prism compensated
to less than 90 fs. Amplitude jitter is less than 0.1%.
