We demonstrate a femtosecond fiber laser incorporating a ReSe2/PVA-based saturable absorber (SA). Using a ReSe2/PVA-based SA, stable ~862-fs pulses are shown to be readily obtained from an erbium-doped fiber ring cavity at 1561.2 nm.

We present a 350-W 940-fs thin-disk oscillator. We achieve this new record-high average power ultrafast oscillator through vacuum operation, multiple passes on the disk, and large pump spot. Systematic power-scaling through multi-pass cavities is discussed.
