Abstract :

Recent progress in fabrication of high-quality thermo-diffusion doped polycrystalline and hot-pressed ceramic Cr 2+ doped ZnSe and ZnS gain media as well as nano and micro-crystalline laser active powders, powders in the liquid suspension, and polymer-film are reported. Demonstration of mid-IR lasing in Cr:ZnSe waveguide structures and the first laser oscillation of the Cr:ZnSe/As 2 S 3 :As 2 Se 3 composite materials will be described. These composite materials are very promising for mid-IR fiber-laser applications. Progress in the technology of fabrication of high-quality uniformly doped TM:ZnSe/S gain elements in combination with proper thermal management and cavities design enabled demonstration of high power; high energy; tunable (1.9-3.3 um), mid- IR Cr:ZnS/Se lasers operating in CW(>20 W), gain-switched (>20 mJ@7 ns) and long pulse(>1 J@7 ms) regimes. We will also report on recent progress in development of new gain media for tunable (3-8 μ m) mid-IR lasers as well as Fe:ZnS/Se lasers operating in CW (>1.5 W), gain-switched (>1 mJ@7 ns@1 kHz) and long-pulse (>0.5 J@200 μ s) regimes. In addition to effective RT mid-IR lasing transition metal (TM) doped II-VI media, being wide band semiconductors, hold potential for direct electrical excitation. Possible promising routes for achieving mid-IR lasing under electrical excitation will be discussed.
