Pooja Sekhar, Connor Fredrick, David Carlson, Scott Diddams
… Frequency combs with mode spacing of 10–20 GHz are critical for increasingly important applications … achieve pulses shorter than 60 fs at a repetition rate of 20 GHz. The same technique can be applied to picosecond … fills a critical gap for transforming any narrowband 10–20 GHz frequency comb into a broadband spectrum for a wide …
