Mid-infrared fiber sources, emitting between 2.5 µm and 5.0 µm, are interesting for their
great potential in several application fields such as material processing, biomedicine …

With growing interest in the mid‐infrared spectral region, dysprosium has recently been
revisited for efficient high‐performance infrared source development. Despite historically …

We report, to the best of our knowledge, the first entirely monolithic dysprosium (Dy)-doped
fluoride fiber laser operating in the mid-IR region. The system delivers 10.1 W at 3.24 μm in …

The mid-infrared (mid-IR) spectral region holds great promise for new laser-based sensing
technologies, based on measuring strong mid-IR molecular absorption features. Practical …

In this review paper some recent advances on optical sensors based on photonic crystal
fibres are reported. The different strategies successfully applied in order to obtain feasible …

We manufactured and characterized a low-loss gain fiber based on high-purity TeO 2–ZnO–
La 2 O 3–Na 2 O undoped glass for 100-μm cladding and TeO 2–ZnO–La 2 O 3–Na 2 O …

We present the first widely tunable passively Q-switched Dy^ 3+-doped ZBLAN fiber laser
around 3 μm pumped at 1.1 μm using PbS nanoparticles as the saturable absorber (SA) to …

We report two new near-infrared pump wavelengths at 0.8 m and 0.9 m for dysprosium (Dy)-
doped mid-infrared fiber lasers, which are free from detrimental pump excited state …

In this Letter, we used a home-made high-power and-brightness random Raman fiber laser
(RRFL) at as the pump to demonstrate free-running and widely tunable operations of …

We report watt-level mid-IR Dy-and Er-doped all-fiber lasers using highly resistant dielectric-
coated fiber mirrors. The fiber pigtail mirror is specifically designed for dichroic operation (ie …
