| 摘 要： | 分析了光纤激光器自相干阵列最简单的情况——两个光纤激光器之间的相位锁定过程。建立了该过程的数学模型，并对它的时间特性和输出光束的模式进行了理论和数值分析，讨论了运行频率差和耦合系数对锁相过程的影响。对于运行频率相等的两个光纤激光器，当两个光纤激光器初始相位差不为0时，相位锁定后的激光器阵列输出模式为异相模；对于运行频率不等的情形，给出了锁相运行对两个光纤激光器运行频率差的要求，并分析了降低这种要求的几种方法。

| Abstract: | Elementary theoretical investigation on self-organized fiber laser array was carried out in this paper. The simplest case for the fiber laser array, i.e., the phase-locking course of two fiber lasers was modeled and analyzed theoretically and numerically. The effect of detuning frequency and coupling coefficient to the phase-locking course was analyzed. For the case that there was no frequency detuning, the array was always in out-of-phase mode. Otherwise, the condition of frequency detuning for phase locking was deduced, and the method for weakening the condition was analyzed in short. |
