The absorption and emission properties of transition metal (TM)-doped zinc chalcogenides
have been investigated to understand their potential application as room-temperature, mid-…

Transition-metal-doped zinc chalcogenide crystals have recently been investigated as
potential mid-infrared lasers. Tetrahedrally coordinated Cr/sup 2+/ ions are especially attractive …

We discuss the upconversion luminescence efficiencies of phosphors that generate red, green,
and blue light. The phosphors studied are single crystals and powders codoped with Er^3…

Lasing of Fe:ZnSe is demonstrated, for the first time to the authors’ knowledge, for temperatures
ranging from 15 to 180 K.?The output wavelength of the Fe:ZnSe laser was observed to …

We 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 …

An experimental study of flow field, surface pressure, and heat transfer rates of a submerged,
turbulent, slot jet impinging normally on a flat plate is presented. Two nozzle-to-surface …

We have used IR excitation to selectively create populations in admixtures of the zeroth‐order
states comprising the ∼3000 cm − 1 ‘‘C–H stretching Fermi triad’’ of benzene. UV spectra …

We report room-temperature operation of an all-solid-state broadly tunable continuous-wave
Cr^ 2+: ZnSe laser. Output power of 250?? mW, an absorbed power slope efficiency of 63 …

Real-time monitoring of the corona-poling process that is used to create a bulk second-order
nonlinear-optical susceptibility was accomplished by observing electrochromic shifts and …

We report light emission around 1 eV (1240 nm) from heterostructures of MoS 2 and WSe 2
transition metal dichalcogenide monolayers. We identify its origin in an interlayer exciton (ILX…
