Optical metrology is one of the key technologies in today's manufacturing industry. In this
article, we provide an insight into optical measurement technologies for precision …

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 …

Abstract Since the mid-(2–20 μm) and far-infrared (20–1000 μm) regions cover the vibration
and rotation characteristic “fingerprint” spectra of many gas molecules and three …

In this paper, we investigate laser emission at 3.4 μm in heavily-erbium-doped fluoride fibers
using dual-wavelength pumping. To this extent, a monolithic 7 mol% erbium-doped fluoride …

We report, as far as we know for the first time, on a pulsed 2.7 µm Er: ZBLAN fiber laser Q-
switched by an electro-optic modulator. The Q-switched operation was achieved with a …

A practical realization of a diode pumped actively Q-switched Er^ 3+-doped fluoride fiber
laser operating near 2.78 μm is reported. For the repetition rate of 100 Hz stable 26 ns …

We report high-energy mid-infrared pulse generation by Q-switching of dysprosium-doped
fiber lasers for the first time. Two different modulation techniques are demonstrated. Firstly …

Abstract Ho 3+/Nd 3+ co-doped fluoroindate glass samples were prepared by melt-
quenching. The absorption and emission spectra, and the differential scanning calorimetry …

A gain-switched pulsed laser based on a commercial, heavily holmium-doped fluoroindate
glass fiber, is designed to emit in the middle-infrared range, at the wavelength. The laser …

We provide a perspective review over the recent development of short-pulsed Raman fiber
lasers (RFLs), which can provide laser emissions with flexible wavelengths for a variety of …
