摘要

摘要: 利用傅里叶光学方法，获得了相干合束远场光强的解析表达式，数值模拟和实验研究了一维锁相二极管激光阵列的相干合束远场特性。研究表明：随着参与合束的发光单元数目的增加，尖峰变锐；同相模的光能集中在更小的立体角内，使得相干合束的亮度增加；异相模的光束能量较为分散，其峰值光强有所降低。系统抖动引起远场峰值光强的降低，破坏了远场的对称性和光束质量。相干合束发光单元数目越多，系统抖动对远场的影响便可以忽略。

Abstract: The analytical expression of the far-field light intensity of coherent combined beams was acquired by Fourier method. The far-field characteristics of the coherent combined beam from the one-dimensional phase-locking laser diode array were numerically simulated and experimentally researched. The results show that the peak becomes sharp with the increase of combined beam quantity; the luminous energy of the cophasal mode centralizes into the smaller spatial angle and makes the illumination of the coherent combined beams increased; the luminous energy of the out-phase mode becomes dispersed and the intensity at its peak is reduced due to the jitter of the system, so the symmetry of far field and quality of the beam is affected; and the more numbers of the beams is combined, the less influence of the system jitter on far field becomes.
