It is shown that in the small distance region of the bar-LD the intensity distribution of the bar-LD is constructed by separate beam spots emitted from each emitter. As the distance of the observation point from the bar-LD increases, the beam spots of the emitters begin to overlap, and even to form a flattop distribution in a large distance region.

结果表明，在距发光面较近处，各emitter辐射的光斑呈分离状；随着距离增加，各光斑开始交叠，甚至出现平顶；当距离足够远，bar型半导体激光器的远场光斑与单个emitter的辐射光斑几乎没有差异。
