Double-heterostructure lasers have been fabricated with an active layer of PbSe sandwiched between cladding layers of PbSrSe. They were operated up to T = 290 K (17 degrees C) in pulse and T = 169 K in cw mode. This is the highest operational temperature in pulsed mode reported for lead salt lasers in the mid-infrared. The emission wavelength tunes with temperature form 8 x 0 mym (T = 20 K) to 4.4 mym (T = 285 K). (IPM)
