Abstract :
A coherent dual comb spectrometer spanning over 45 THz in the NIR was constructed from broadened erbium fiber lasers. Gas phase water, methane, and acetylene spectra were measured and characterized toward establishing absolute frequency references. Work of the U.S. government, not subject to copyright.
