It is demonstrated that the frequency drift will break up the phase-locked state of the laser array and induce the spatial instability of the far-field intensity due to phase noise. It is also found that although the evanescent coupling between elementary lasers can restrain these effects to some extent, the restrainability is too limited to be effective when the frequency drift is relatively strong.
通过对耦合激光器阵列动力学方程的数值研究发现,频率漂移将破坏激光器阵列的锁相状态,并引入相位噪声,导致输出远场光强分布不稳定;研究还发现:倏逝波耦合能够对频率漂移的影响起到一定的抑制作用,但这种抑制只在频率漂移较弱时才有效,因此,如果将该阵列用于光束合成,加入相应的抗干扰措施还是很必要的。
