Title: A coherent dual-comb spectrometer at 3.4 υm for accurate line center measurement of methane
Published: October 10, 2011
Abstract: Doppler-broadened methane lines around 3.4 υm are measured with a coherent dual-comb spectrometer with an absolute-frequency axis. The obtained accuracy of the line-center frequency is 300 kHz, about 1 part per thousand of the linewidth.
