摘要：
A phase-locking fiber laser array with up to 60 W of coherent output power based on two large-core fiber is reported. The slope efficiency of the in-phase mode is 37%. For the two core space cases, the steady high-contrast interference strips are observed. When the whole system operates under high pump power level, no thermal effects for the spatial filter have been observed, which means that we can increase the coherent output power further by increasing the individual fiber laser power.
