Abstract

We demonstrate both numerically and experimentally that self-phase modulation-enabled spectral selection generates wavelength tunable energetic pulses that are tightly synchronized to the excitation pulses. The synchronization quantified by relative timing jitter is at the 100-as precision level, at least 10 times lower than can be achieved by Raman soliton pulses derived from the same source laser. This ultrafast two-color source is suitable for many important applications that require tight pulse synchronization.
