چکیده
The technology of hot-pressed Cr(2+):ZnSe ceramic preparation is reported. Comparative gain-switched lasing of hot-pressed ceramic and CVD grown Cr(2+):ZnSe samples with slope efficiencies up to 10% and output energies up to 2 mJ were demonstrated. This is a milestone in the development of future large scale mid-IR laser systems based on ceramic TM(2+):II-VI materials. This evolving technology has excellent potential as media for practical low cost, high power mid-IR laser applications.

متن کامل3.9-4.8 μm gain-switched lasing of Fe:ZnSe at room temperature
We report a room temperature Fe:ZnSe laser in gain-switched operation and tuning over the 3.9 4.8μm spectral range. Mid-IR emission of Fe:ZnSe was studied under three regimes of excitation: ordinary optical (2.92μm) excitation of T2 excited state of Fe; excitation via E level of Cr co-dopant (1.56μm); and excitation via photo-ionization transition of Fe (0.532μm). The energy transfer from Cr (E...

Efficient continuous-wave (cw) lasing of Cr(2+):ZnS and Cr(2+):ZnSe crystals in external hemispherical cavities and in a microchip configuration under Er-fiber-laser pumping at room temperature are reported. The key result is what is believed to be the first successful demonstration of cw Cr(2+):ZnS and Cr(2+):ZnSe microchip lasers with maximum output powers of 63 and 100 mW at 2320 and 2520 nm...
متن کاملBroadly tunable compact continuous-wave Cr(2+):ZnS laser.
We report the development of a continuous-wave, room-temperature Cr(2+) ZnS laser that is compact and tunable over 700 nm. The laser is pumped by a diode-pumped Er-fiber laser and generates 0.7 W of linearly polarized radiation at 2.35microm , at up to 40% slope efficiency. Cr(2+) ZnS directly diode-pumped at 1.6microm yields polarized radiation that is tunable over 400 nm at up to 25 mW of out...
