We present chalcogenide (Ch) glass-based all-fiber application-specific microstructured optical fibers (MOFs)-based devices like all-fiber efficient discrete and broad-band light sources as well as fibers for distortion free high power light guidance in the mid-IR spectral regime. For new source generation, nonlinearities and dispersion of index guided Ch-MOFs were suitably tailored through structural optimization, while for high power guidance, an ultra large mode area fiber design and a second design for distortion free parabolic pulse generation will be described.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.
