Abstract: The use of mid-infrared fiber in the 2–12 μm spectral range has been widespread in a variety of application areas, including nonlinear optics, telecommunications, medical, and the military. Night vision, surveillance, and missile guidance are some of the military uses. Mid-infrared fiber lasers have advanced significantly over the past few decades thanks to advancements in pumping regimes, fiber components, and other associated technologies, and progressively caught up to or even surpassed classical lasers in some lasing performance. The confinement loss spectra of mid-infrared fiber spanning the wavelength range of 2μm to 12 μm were simulated and examined.......
