Abstract
This paper presents a novel upconversion time-stretch infrared spectroscopy (UC-TSIR) technique that significantly increases the speed and resolution of broadband mid-infrared (MIR) spectroscopy. By incorporating a nonlinear upconversion process, the technique achieves more than 1000 spectral elements, exceeding the capabilities of existing methods like Fourier-transform infrared (FTIR) spectroscopy. The researchers demonstrate high-resolution spectroscopy of methane gas molecules, highlighting the technique's potential for various applications in molecular science.
