TLDR
In this paper, a highly nonlinear Holey fiber for making a mid-infrared light source at 4.36 µm was designed and a solid-core chalcogenide-based index-guided Holey microstructured optical fiber with circular air holes was exploited to numerically demonstrate wavelength translation via four-wave mixing.Abstract:
We report the design of a highly nonlinear holey fiber for making a mid-infrared light source at 4.36 μm. A solid-core chalcogenide-based index-guided holey microstructured optical fiber with circular air holes has been exploited to numerically demonstrate wavelength translation via four-wave mixing. We employ a thulium-doped fiber laser as the pump with a power of 5 W. Our simulations indicate that a maximum parametric gain of 20.5 dB with a bandwidth of 16 nm is achievable in this designed fiber, resulting in a power conversion efficiency of more than 17.6%.read more

TL;DR: The development of a new generation of solid-state lasers tunable over a wide range in the mid-IR range of the spectrum with parametric generation of light and a combination of high radiation intensity and relatively low pulse energy at high repetition frequency opens up new possibilities for less-invasive, high-precision, laser surgery, first and foremost, in ophthamology and neuro- and cardiosurgery.
