Mid-infrared supercontinuum generation in supercritical xenon-filled hollow-core negative curvature fibers.
We present an investigation on the generation of supercontinuum in the mid-infrared (mid-IR) spectral region. Namely, we study a silica-based anti-resonant hollow-core fiber which has good guidance properties in the mid-IR filled with supercritical xenon providing the necessary high nonlinearity. Our numerical study shows that by launching a 200 nJ pump of 100 fs centered at 3.70 μm, a supercontinuum that spans from 1.85 to 5.20 μm can be generated. Such sources are potentially useful for applications, such as the remote sensing of various molecules, medical imaging diagnosis, and surgery.
