Single devices with active diameters of 500 m show high output powers of 1.95 W at room temperature. Its threshold current is 510 mA  and the maximum spatially averaged optical power density is 0.93 kW/cm2. A 16 elements array with 200m aperture size (250m center spacing) of individual elements shows a CW output power of 1.21 W at room temperature  resulting in a average optical power density of 1KW/cm2. The threshold current of the array is 1.32A and the lasing peak wavelength is 981.9 nm. The distinction of emission spectrums between the single device and the array is discussed.
