The development of mid-IR diode lasers capable of operation above 77 K in the 6.5 to 13 am range will lead to many applications that have been previously precluded by stringent cryogenic cooling requirements. Commercial applications include low-cost, high-performance systems for industrial and air pollution monitoring, medical diagnostics, and other analytical applications.lead-salts, tunable diode lasers, PbSnTe, single-mode, buried heterostructure, molecular beam epitaxy
