Dual-comb spectroscopy is a powerful spectroscopic technique that utilizes two frequency combs to rapidly acquire high-resolution spectra. This technique allows for fast and accurate measurement of molecular absorption and emission spectra, making it particularly useful for applications in environmental monitoring, material analysis, and chemical sensing. Dual-comb spectroscopy offers several advantages over traditional spectroscopic methods, including higher resolution, faster data acquisition, and reduced sensitivity to environmental noise. Researchers are actively exploring new ways to optimize and expand the capabilities of dual-comb spectroscopy for a wide range of scientific and industrial applications.
