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 tune with temperature from 3.98 {mu}m at 15 K to 4.54 {mu}m at 180 K. With an Er:YAG laser operating at 2.698 {mu}m as the pump source, a maximum energy per pulse of 12 {mu}J at 130 K was produced. Laser slope efficiencies of 3.2% at 19 K and 8.2% at 150 K were determined for an output coupling of 0.6%. A laser emission linewidth of 0.007 {mu}m at 3.98 {mu}m was measured at 15 K. Absorption and emission spectra and emission lifetimes for Fe:ZnSe are also discussed. (c) 1999 Optical Society of America.
