Popis: The optimization of MBE growth conditions and layer structures for room temperature operation of 2.26mm AlGaAsSb/GaInAsSb laser structures is investigated. Index guided triple quantum well large optical cavity diode lasers with 64mm � 1000mm cavities and high reflection/antireflection coated facets reveal a cw output power of 350 mW at T ¼ 280 K. An internal quantum efficiency Zi of 69%, internal losses ai of 7.7 cm � 1 and a threshold current density for infinite cavity length of j1 ¼ 144 A/cm 2 are obtained for this structure. # 2001 Elsevier Science B.V.
