Distributed feedback Pb/sub 1//sub - x/Sn/sub x/Te double-heterostructure lasers grown by molecular-beam epitaxy with cw operation up to 50 K are reported. The grating of 1.1-..mu..m periodicity operates in the first Bragg order near 800 cm/sup -1/ (12.5 ..mu..m). Single-mode operation is obtained over a wide range of diode current and heat-sink temperature. Continuous current tuning of mode frequency up to 7 cm/sup -1/ is obtained, and by varying both diode current and heat-sink temperature complete coverage of the range 795--806.5 cm/sup -1/ is demonstrated.
