Theoretic analysis on self-organized coherence of fiber laser array
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-ofphase mode.Otherwise,the condition of frequency detuning for phase locking was deduced,and the method for weakening the condition was analyzed in short.
