Far fields of super-modes (SMs) from an external cavity phase locked high power laser diode array (LDA) are studied. The super-mode far-field lobes shows periodical distribution, and there are spikes with the equivalent spacing between two lobes. The intensity of the spike is generally much less than that of the lobe. The angular spacing between two neighboring pairs of lobes is equal to the ratio of lasing wavelength λ to the distance d between the centers of two adjacent emitters, and the angular spacing of the lobes of each pair depends on the order of super-mode. For the lowest order super-mode (LSM) and highest order super-mode (HSM), there are even larger spikes between two closely spaced lobes resulting in composite lobes so that the number of lobes is reduced to a half of that of the other orders super-modes. For other super-modes, the intensity of the spike nearer to the lobe is larger and that of the farther is smaller. The far-field distribution of the lowest order super-mode is similar to that of the highest order one but of an angular diapalcement of λ/(2d).
