Popis: Seeded free growth method with physical transport was used for preparation of large-size II—VI single crystals uniformly doped by transition metals directly during the growth. The grown crystals possess small intrinsic losses. Based on these crystals new results on development of mid-IR lasers were achieved. With the CdSe:Cr crystal pumped at the room temperature (RT) by a continuous wave (CW) 1.908-μm thulium fiber laser, output laser power at 2.6 μm was increased up to 1.7 W. CW lasing from the ZnSe:Fe crystal was achieved using the 2.97-μm CW Cr 2+ :CdSe laser as a pump source. In this case the output power as high as 0.2 W was obtained at 4.1 μm and T=80 K. Broad spectral tuning of the Cr 2+ :CdSe (2.26-3.61 μm) and Fe 2+ :ZnSe (3.95-5.05 μm) lasers was achieved at RT in the pulsed operation. The RT laser action from CdS:Cr and CdSe:Fe was demonstrated for the first time. The output power of the CW Cr +2 :CdS laser was 0.81 W. The pulsed Fe 2+ :CdSe laser was tuned in the 4.6-5.9 μm spectral range.
