Abstract

Frequency-stabilized mid-infrared lasers are valuable tools for precision molecular spectroscopy. However, their implementation remains limited by complicated stabilization schemes. Here we achieve optical self-locking of a quantum cascade laser to the resonant leak-out field of a highly mode-matched two-mirror cavity. The result is a simple approach to achieving stable frequencies from high-powered mid-infrared lasers. For short time scales (${\lt}{0.1}\;{\rm{ms}}$), we report a linewidth reduction factor of ${{3}} \times {{1}}{{{0}}^{- 6}}$ to a linewidth of 12 Hz. Furthermore, we demonstrate two-photon cavity-enhanced absorption spectroscopy of an ${{\rm{N}}_2}{\rm{O}}$ overtone transition near a wavelength of 4.53 µm.
