All-solid-state femtosecond source at 1.55 microm.
We report on a stretched-pulse additive-pulse mode-locked erbium-doped fiber laser pumped by a masteroscillator/power-amplifier diode at 980 nm. This laser operates at 1.55 microm and puts out as much as 90 mW of average power at 40 MHz with pulse widths that are prism compensated to less than 90 fs. Amplitude jitter is less than 0.1%.
