Abstract

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 3.98μm at 15 K to 4.54μm at 180 K. With an Er:YAG laser operating at 2.698μm as the pump source, a maximum energy per pulse of 12μJ 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 0.007μm at 3.98μm was measured at 15 K. Absorption and emission spectra and emission lifetimes for Fe:ZnSe are also discussed.
