We report the experimental demonstration of nearly transform-limited dual-wavelength pulse trains at a 5-GHz repetition rate that were generated by spectral filtering of an intracavity 2.5-GHz frequency-modulated Er–Yb bulk-glass laser operating at the 1533-nm wavelength. Highly stable dual-wavelength pulse trains with ~165-GHz frequency separation, ~48-ps pulse duration, and ~1-mW average single-mode fiber-coupled power were obtained.
