1 GHz dual-comb spectrometer for fast and broadband measurements

Dual-frequency comb spectroscopy permits broadband precision spectroscopic measurements with short acquisition time. A dramatic improvement of the maximal spectral bandwidth and the minimal measurement time can be expected when the lasers’ pulse repetition rate is increased, owing to a quadratic dependence (Nyquist criterion). This white paper demonstrates a dual-comb system operating at a high repetition rate of 1 GHz based on mature, digitally-controlled, low-noise modelocked lasers
