We show the optically pumped results for two samples with room temperature target wavelengths of 2.5 and 2.7 /spl mu/m. The wafers are composed of 4 compressively strained QWs sandwiched in a 1 /spl mu/m AlGaInSb waveguide region. The samples were cleaved into 1-mm cavity lengths and pumped with 222-/spl mu/m stripe widths. The pump is a 980 nm array using 50 /spl mu/s pulses and 5% duty cycle. The 2.5 /spl mu/m wavelength sample is composed of 100 /spl Aring/ Ga/sub 0.60/In/sub 0.40/Sb wells with Al/sub 0.20/Ga/sub 0.48/In/sub 0.32/Sb barriers.
