Fig. 1From: Low-noise transfer of the spectral purity of an optical comb line using a feedforward scheme(Top) Phase noise power spectral density (PN-PSD) of the two commercial mode-locked lasers used in the experiment measured at a high harmonic of the repetition rate at around 10 GHz. (Bottom) Corresponding integrated timing jitter (integration from 1 kHz to 10 MHz). The dashed black lines indicate the noise floor of the measurementBack to article page
