| contents | Mid-infrared frequency comb spectroscopy enables measurement of molecular at megahertz spectral resolution, sub-hertz frequency accuracy and microsecond acquisition speed. However, the widespread adoption of this technique has been hindered by the complexity and alignment sensitivity of mid-infrared frequency comb sources. Leveraging the underexplored mid-infrared window of silica fibers presents a promising approach to address these challenges. In this study, we present the first experimental demonstration and quantitative numerical description of mid-infrared frequency comb generation in silica fibers. Our all-silica-fiber frequency comb spans over two octaves (0.8 $μ$m to 3.5 $μ$m) with a power output of 100 mW in the mid-infrared region. The amplified quantum noise is suppressed using four-cycle (25 fs) driving pulses, with the carrier-envelope offset frequency exhibiting a signal-to-noise ratio of 40 dB and a free-running bandwidth of 90 kHz. Our developed model provides quantitative guidelines for mid-infrared frequency comb generation in silica fibers, enabling all-fiber frequency comb spectroscopy in diverse fields such as organic synthesis, pharmacokinetics processes, and environmental monitoring. |
