• Abstract: The dynamic behavior of a two-dimensional 3 × 3 planar space coupled multimode laser array is simulated. The results show that the total intensity and the intensity of each corresponding mode between the sub diagonal of the laser array and the paired laser pairs (laser 2 and 4, laser 3 and 7, laser 6 and laser 8) parallel to the sub diagonal can achieve chaos synchronization, and there is mode competition between the modes of the same laser. By calculating and analyzing the power spectrum and Lyapunov exponent, the laser system is in chaos. 对两维 3×3 平面型空间耦合多模激光阵列的动力学行为进行了数值模 拟。研究结果表明，处于激光阵列的次对角线及平行于次对角线的配对激光对（激 光 2 和 4，激光 3 和 7，激光 6 和 8）之间的总强度和各对应模式的强度可以实 现混沌同步，且同台激光各模式之间存在模式竞争。通过计算和分析功率谱和 李雅普诺夫指数，该激光系统确实处于混沌状态。
