Abstract: We generate mode-locked picosecond pulses near 1110 nm
by spectrally slicing and reamplifying an octave-spanning supercontinuum
source pumped at 1550 nm. The 1110 nm pulses are near transform-limited,
with 1.7 ps duration over their 1.2 nm bandwidth, and exhibit high interpulse
coherence. Both the supercontinuum source and the pulse synthesis system
are implemented completely in fiber. The versatile source construction
suggests that pulse synthesis from sliced supercontinuum may be a useful
technique across the 1000 - 2000 nm wavelength range.
