Abstract
To coherently couple low-power lasers with reliable beam quality in order to achieve a high-power output is a desirable goal lor different types of lasers. Unfortunately theoretical studies revealed the instability of the phase-locked state over a wide range of system parameters which gives rise to various types of interesting but mostly undersired temporal and spatial dynamics. Therefore phase locking of the separate emitters by external means remains a crucial task. While many of the introduced phase locking setups are of complex nature we introduce phase locking into a multicore fiber laser [1] by a simple filler mirror (FM)
