Double‐Heterostructure lasers have been fabricated with an active layer of PbSe sandwiched between cladding layers of Pb1−x Srx Se. They were operated up to T=290 K (17 °C) in pulsed 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 from 8.0 μm (T=20 K) to 4.4 μm (T=285 K).
