| 摘 要： | 报道了一个相位锁定的光纤激光器阵列获得60W的输出,同相模式输出时的斜率效率为37%。对于两种不同的纤芯距离都观测到稳定的高对比度干涉条纹。整个系统在高功率操作时,所用的空间滤波器没有观察到明显的热问题,这充分说明了采用这种方法能够进一步提高相干输出功率。

| Abstract: | 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. |
