Distributed Bragg reflector Pb/sub 1/..sqrt../sub x/Sn/sub x/SePb/sub 1/..sqrt../sub x/..sqrt../sub y/Eu/sub y/Sn/sub x/Se double heterostructure stripe geometry diode lasers were fabricated using molecular-beam epitaxy. Single-mode cw operation at about 7.8 ..mu..m was obtained for heat-sink temperatures in the range 25--75 K. the single-mode continuous tuning range was 10 cm/sup -1/. Tuning the diodes via the injection current, a range of 24 cm/sup -1/ was completely covered with single-mode emission. The reason for this wide tuning range was mode hopping to lower frequencies rather than the usual hopping to higher frequencies
