Abstract
The mid-infrared (mid-IR) spectral region holds many opportunities for new optical technologies and potentially transformative applications in medicine, manufacturing and defence. To date, however, such applications have been held back by a lack of high-brightness coherent light sources at mid-IR wavelengths with sufficient flexibility and robustness for practical deployment. Rare-earth-doped fluoride fibers are currently emerging as a promising and highly versatile platform for mid-IR laser technology and in the past few years, there has been particularly strong progress using the dysprosium ion, which offers broadband emission from ∼2.7–3.5 µm and even has potential to enable a new class of 4-µm fiber lasers. In this presentation, we review the spectroscopy of dysprosium-doped fluoride fibers and present recent developments of compact, high-power, broadly tunable mid-IR sources, in addition to offering an outlook towards further developments and practical applications.
