    • A incoherent, optically-uncoupled laser array (40, 60) for an electro-optic line modulator, a line printer or the like, comprises a plurality of spatial laser emitters (54) having high power density and a uniform far field emission pattern. Structural means is provided in the array to permit the spacing of the emitters sufficiently close to provide a uniform far field emission pattern without permittng phase-locking between adjacent emitters of the array. The structural means may comprise geometric lateral and diagonal displacement (43) of adjacent optical cavities of the laser elements. Alternatively, the structural means may comprise a plurality of spatially-­disposed isolation regions (72) extending across the laser array and extending into the laser array a distance sufficient to isolate the optical cavities (78) of the laser elements from one another, to prevent optical coupling between adjacent laser elements. The spatial isolation regions may be formed into the fabricated laser array using impurity-induced disordering (IID).
    • 激光器阵列(40)具有高功率密度的一组空间发射器(54)。 该结构提供激光元件的相邻光学腔的几何横向和对角位移(43)。 或者,一组空间上设置的隔离区域延伸穿过该阵列并且足以将激光元件的光学腔彼此隔离以防止相邻的隔离区域之间的光学耦合。 隔离区域可以使用杂质诱导的无序化形成制造的激光器阵列。
