TL;DR: In this paper, the absorption and emission properties of transition metal (TM)-doped zinc chalcogenides have been investigated to understand their potential application as room-temperature, mid-infrared tunable laser media.

TL;DR: In this article, the authors used rotational cooling of molecules to ∼5 K by supersonic expansion and state-selective, multilevel saturation spectroscopy to obtain high-resolution spectra of the fundamental and first and second overtone transitions of C-H stretching modes in ground-electronic-state benzene and its dimer.

TL;DR: In this article, the upconversion luminescence efficiencies of phosphors that generate red, green, and blue light were discussed. But the main contribution is the quantitative measurement of this upcon conversion efficiency, based on the use of a calibrated integrating sphere, determination of the fraction of pump light absorbed, and careful control of the pump-laser-beam profile.

TL;DR: In this paper, transition-metal-doped zinc chalcogenide (ZnS:Cr) and ZnSe:Cr (using a MgF/sub 2/:Co/sup 2+/ laser pump source) were used for mid-infrared laser applications.
