The fabrication and characteristics of the first Hg(1-x)Cd(x)Te double heterostructure mid-IR injection laser (Zandian et al., 1991) are described in detail, and new results on an expanded range of operation of this laser are presented. Three new double heterostructures were grown, which all produced working lasers operating under pulsed current at temperatures between 40 and 90 K. At 77 K, their emission wavelengths were 2.9, 3.4, and 3.9 microns; the lowest threshold current density measured was 521 A/sq cm, very close to that predicted by a numerical calculation.
