Formulas for the radiated intensity distributions of coherent and incoherent combined Lorentz-Gaussian beam array are
respectively derived by utilizing representations of the cross-spectral density of the far field. Intensity distributions
versus azimuth angles are depicted by numerical examples. Effects of beam array numbers and separate distances etc. on
far-field radiated profiles are shown and analyzed. Comparisons between the phenomenon respectively induced by
coherent and incoherent combinations of Lorentz-Gaussian beams are also made and further discussed. These results
may provide potential applications in producing high-power double heterojunction laser arrays.
