Analyse its pressure distribution and velocity vector  which provides the optimal size for the manufacture of the ejectors and a theoretical basis for experiment.

This array is composed of 5 symmetrically-arranged elements of 200m  150m and 100m-diameter  with the center spacings of 300m and 250m respectively. The maximum power is 880mW at a current of 4A  corresponding to lKW/cm2 average optical power density. The differential resistance is 0.09 with a threshold of 0.56A. The novel array is compared with a 300m-aperture-size single device and a 44 2-D array with 50m element aperture size and 250m centre spacing. The three devices have the same lasing area. The conclusion is that the novel array is better in the property of output power  threshold current  lasing spectra  far-field distribution etc. 2008 SPIE.
