We demonstrate a novel scheme based on active mode locking combined with four-wave mixing (FWM) to generate ultra-short pulse trains at high repetition rate with multiple wavelengths for applications in various fields. The obtained six wavelengths display high uniformity both in temporal and frequency domain. Pulses at each wavelength are mode locked with pulse duration of similar to 44.37 ps, signal-to-noise ratio (SNR) of similar to 47.89 dB, root-mean-square (RMS) timing jitter of similar to 552.7 fs, and the time-bandwidth product of similar to 0.68 at repetition rate of 1 GHz. The experimental results show this scheme has promising usage in optical communications, optical networks, and fiber sensing.
