Key Points

High-resolution gas spectroscopy was achieved using a dual-comb laser system, and it emphasizes the effectiveness of spectral interleaving.
The dual-comb system displayed an operational frequency of 1 GHz, which enhances spectral precision in gas analysis.
The use of a single-cavity Yb:CaF2 laser allows for reliable probing, providing significant advancements in spectroscopy techniques.
Combining a controlled probing comb with a free-running spectrometer offers flexibility and improved results in measuring gas emissions.

Implication

Demonstrating high-resolution gas spectroscopy for acetylene with a dual-comb laser, highlighting its innovative design.

Abstract

We demonstrate high-resolution gas spectroscopy of acetylene using a single-cavity, dual-comb Yb:CaF 2 laser operating at 1 GHz. Leveraging spectral interleaving, the system combines a fully controlled probing comb with a free-running spectrometer comb.
