Infrared (IR) diode lasers have been made by growing heterostructures or graded structures of Pb/sub 1-//sub x/Eu/sub x/Se. This IV-VI ternary has a small lattice variation within the IR band-gap range. Double-heterostructure lasers with PbSe active layers were operated up to T = 174 K cw and 220 K pulsed mode; they reached the highest cw operation temperature reported for this type of laser in the mid IR. Their tuning range was 7.8--5.7 ..mu..m cw. Lasers with the ternary as the active layer were operated up to the shortest wavelength of 2.88 ..mu..m at 100 K cw. At present lasers made by molecular beam epitaxy of this material cover the widest wavelength region at T>77 K around 5 ..mu..m in cw operation.
