For a decade the femtosecond laser based frequency comb has played a key role in high precision optical frequency metrology.While often referred to as a precise optical frequency ruler, its tick marks are in fact too densely spaced for direct observation and individual use, limiting important applications in spectroscopy, astronomy and ultrafast electromagnetic waveform control. Here, we report a novel femtosecond laser frequency comb with 10GHz repetition rate that creates a stabilized output spectrum with coverage from 470 nm to 1130 nm whose individual elements are directly resolved with a grating spectrometer.
