Molecular jet spectroscopy has been predominantly performed using electronic excitation methods such as REMPI and LIF. However, for small molecules like CO2, the large electronic transition energy poses a significant challenge due to the requirement for short-wavelength light sources. In this study, we successfully demonstrated all-optical nonlinear spectroscopy of a molecular jet in the mid-infrared region.
