A collaboration between our group and that of  my colleague, late John V. Badding has led to the first demonstration of fiber lasers with ZnSe core.  These ZnSe cores, deposited inside silica capillary using High Pressure Chemical Vapor Deposition invented by Badding group and doped with either Cr2+ or Fe2+ are ideal for infrared emission from 2-4 micron wavelengths.  In collaboration with Ken Schepler, Gary Cook, Sean McDaniel, and Mike Coco from the Air Force, we have indeed demonstrated the first such fiber lasers.  The Cr2+:ZnSe work has appeared in Optical Materials Express recently.  The Fe2+:ZnSe work is published in Optics Express.
