摘要 理论分析了利用自成像共焦腔实现激光列阵相干合成的物理模型,对自成像共焦腔的一维相干合成和二维相干合成进行了模拟仿真计算,得到腔内场的强度分布图样.在此基础上,研究了空间滤波器在相干合成中实现模式选择的机理,并讨论滤波器的设计对相干合成及模式选择的影响,分别对一维相干合成和二维相干合成的情况,仿真计算了输出功率与滤波器位置和宽度的关系,为实验提供了理论依据. The mode of coherent combination of laser arrays is set up based on self-imaging confocal resonator. One-dimensional coherent combination and two-dimensional coherent combination are calculated and the intensity distribution of the field is obtained. Spatial filter used for mode selection is studied. Besides, the effect of the place and the width of the special filter on the coherent combination is analyzed, which gives the basis to the experiment.
