Abstract: We demonstrate a dual-color 1.55/1.03 μm all-fiber femtosecond laser exhibiting sub-femtosecond relative timing jitter. The 1.03 μm channel is generated via resonant dispersive-wave emission in a short segment of highly nonlinear fiber pumped by a sub-30-fs, 1.5-μm laser. Despite the commonly assumed high intrinsic noise of dispersive-wave generation in highly nonlinear fiber, we show that optimized nonlinear-conversion conditions combined with a low-noise pump enable sub-femtosecond timing synchronization between the dispersive wave and the signal at 1.5 μm. This work demonstrates the feasibility of low-jitter multicolor ultrafast sources spanning fiber-amplifier gain bands at 1.0 μm, 1.5 μm, and beyond 1.8 μm in a fully integrated all-fiber architecture without active feedback control.
