Frequency comb UV spectroscopy with one million resolved comb lines
Abstract
We perform dual-comb spectroscopy in two UV bands: 325-342 nm and 372-410 nm, corresponding to the 7th and 6th harmonics of a dual-comb 2.35-μm laser source, and simultaneously resolve ~500,000 and ~1,000,000 comb lines spaced by 80 MHz respectively.
