Gain-guided Ga0.84In0.16As0.14Sb0.86/Al0.75Ga0.25As0.06Sb094 double-heterostructure lasers emitting at approximately 2.2-mu-m have been operated cw at heat sink temperatures up to 30-degrees-C. The maximum output powers obtained at 5 and 20-degrees-C were 10.5 and 4.6 mW/facet, respectively. For pulsed operation of broad-stripe lasers 300-mu-m wide and 1000-mu-m long, the threshold current density was as low as 940 A/cm2 the lowest room-temperature value reported for diode lasers emitting beyond 2-mu-m.
