Continuous operation over 1500 h at 77 K has been achieved by use of a PbTe/Pb/sub 0.93/Sn/sub 0.07/Te double-heterostructure laser which was grown using the liquid-phase-epitaxy method. The cw threshold current changed only about 3% during the first 200 h. It is concluded that the lifetime of PbTe/PbSnTe double-heterostructure lasers at 77 K is fundamentally very long.
