Absolute-frequency THz dual-comb instrument: a scalable and high-resolution spectrometer based on electro-optic comb generation

Not Accessible

Your library or personal account may give you access

Abstract

We present a compact and robust absolute-frequency THz dual-comb spectrometer based on electro-optic modulators that provides ultra-narrow linewidth teeth, a total control over both central and repetition frequencies and a high measurement speed.
