| 摘 要： | 报道了32路光纤激光相干阵列的相位锁定实验研究。搭建了32路光纤激光相干阵列实验系统，基于现场可编程逻辑阵列（FPGA）设计制作了高速高精度相位控制器。当相位控制器执行随机并行梯度下降（SPGD）算法对各路激光的相位进行锁定时，相干阵列输出的激光功率与不进行相位锁定时相比提高了约26倍。

| Abstract: | An experiment of phase locking of 32 fiber lasers is reported. A coherent array of 32 fiber lasers is built and a high-speed high-precision phase controller is designed based on field programmable gate array(FPGA). When the stochastic parallel gradient descent (SPGD) algorithm is implemented by the phase controller, the phases of the fiber lasers are locked and the output power of the combined laser is enhanced by a factor of about 26. |

| Keywords: | coherent beam combination fiber laser phase locking stochastic parallel gradient descent algorithm |
