Abstract

In order to acquire high-resolution molecular absorption spectrum, a measurement system consisting of two Erbium-doped fiber optical frequency combs based on multi-heterodyne detection method is established. Preliminary result shows that the specific line in the RF spectrum corresponding to 6452.59 cm^-1 in the optical region, where there is an error of 0.14 cm^-1 compared with the simulation result. And the further improvement of this system will be discussed in the end.
