Ga2O3 is attractive for power devices and solar-blind ultraviolet photodetectors due to its
ultra-wide bandgap, large breakdown field, and favorable stability. However, it is difficult to …

Abstract Mid‐infrared (mid‐IR) ultrafast lasers are widely employed in biomedicine,
molecular spectroscopy, material processing, and nonlinear optics. With the improvement of …

Enabling broad tunability, high peak and average power, ultrashort pulse duration, and all
known modes of laser operation-transition-metal (TM)-doped II-VI chalcogenides are the …

Transition metal (TM) doped II-VI chalcogenide laser materials offer a unique blend of
physical, spectroscopic, and technological parameters that make them the gain media of …

We review the latest breakthroughs in ultrafast fiber laser technology in the mid-IR
wavelength range≥ 2 μm. In particular, we concentrate on two novel laser systems built …

In this study, we proposed a numerical model incorporating ion clustering effect for an Er 3+-
doped ZBLAN fiber laser. Our proposed model does not use weak-interaction (WI) energy …

We experimentally demonstrate in a difference-frequency generation mid-infrared frequency
comb source the effect of temporal overlap between pump-and signal-pulse to the relative …

We report on a comprehensive characterization of Cr^ 2+-doped CdSe single crystal as an
efficient active material for tunable laser applications in the mid-infrared spectral region …

We report for the first time multi-watt mid-infrared supercontinuum (SC) output from a
dehydrated tellurite step-index fiber. The tellurite glass preform is melted in a dry …

Pumping mid-IR optical parametric oscillators near 1 μm is attractive for its simplicity and
power scaling capability. To this aim, wide bandgap non-oxide nonlinear crystals are …
