Abstract

Phase locking of coupled fiber lasers requires that there exists at least one longitudinal-mode common to all lasers within their bandwidth. As the number of coupled lasers increases, the probability of finding such a longitudinal-mode drops exponentially [1]. Nevertheless, since the length and the corresponding longitudinal-modes of each fiber laser fluctuate randomly due to acoustic and thermal noises, there is a finite probability for having an instantaneous common longitudinal-mode. Due to mode competition, when such a rare event occurs, the lasers lock to this specific longitudinal-mode, resulting in a high fringe visibility interference pattern [2].
