Light generated by optical frequency division consists of a phase-locked optical harmonics 1f, 2f, 3f ... with an extremely wide frequency spacing above 100 THz. By controlling the phases and amplitudes of these harmonics, one can generate an ultrashort pulse train with an ultrahigh repetition rate above 100 THz. In this presentation, we will talk about the generation of the five phased-locked harmonics (1f: 2403 nm, 2f: 1202 nm, 3f: 801 nm, 4f: 600 nm, 5f: 481 nm) and the synthesis of the ultrashort pulse train with 125 THz repetition rate.
