Scattering of light by disordered structures is a common phenomenon in our daily life. For
many scientific applications, scattering is often treated as a detrimental effect. However …

After a brief examination of known insulating laser crystals and the stimulated emission
channels of their generating activator ions, this article reviews recent advances in 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 …

Laserlike emission in powders of praseodymium-doped oxisulfides of yttrium, lanthanum,
and gadolinium has been reported in References [1, 2] under laser pumping (at different …

Recent progress in chromium and iron doped II‐VI semiconductor materials makes them the
laser sources of choice when one needs a compact system with tunability over 1.9–5.1 μm …

The paper reviews material, spectroscopic, laser and nonlinear optical properties of wide-
band Cr2+-doped II–VI materials. The strong revival of research interest in these materials is …

We review a novel class of femtosecond Cr 2+-doped ZnSe and ZnS lasers, which operates
in a very important for applications wavelength range between 2 and 3.5 μm and which …

In this Letter, a watt-level laser diode (LD)-pumped∼ 2.3-µm (on the^ 3H_4?^ 3H_5 quasi-
four-level transition) laser is reported based on a 1.5 at.% a-cut Tm: YVO_4 crystal. The …

The 3 H 4→ 3 H 5 transition of Thulium ions (Tm 3+), which features laser emission at~ 2.3
μm is studied in details. We revise the conditions for efficient laser operation using a rate …

Ultrabroadband infrared transition metal ion-doped solid-state lasers have come of age and
are increasingly being used in trace gas monitoring, remote sensing, telecommunications …
