Fibre laser based mid infrared sources and their applications
The mid-infrared (mid-IR) spectral region of 2-20 µm contains strong characteristic vibrational transitions of many important molecules and incorporates the atmospheric transmission window, which makes it crucial for applications in spectroscopy, materials processing, chemical and biomolecular sensing, security and environmental monitoring. However, this wavelength range is difficult to access directly using traditional laser materials and cavity implementations.
