The method of ''instantaneous'' evaporation in vacuum was used in the fabrication of heterojunction lasers based on Pb/sub 1-x/Sn/sub x/Te and characterized by one-sided confinement in the spectral range 9--16 ..mu... Heterostructures were formed by growing epitaxial n-type indium-doped (x=0.14, 0.18) or bismuth-doped (x=0.20) films on p-type thallium-doped PbTe substrates. Low-temperature epitaxy (< or approx. =350 /sup 0/C) was used to prepare also undoped n-type Pb/sub 0.88/Sn/sub 0.12/Te films on undoped p-type PbTe substrates. The threshold current density was optimized by varying the thickness of the active region and the majority-carrier density in this region.
