搭建了一台全光纤结构的光纤激光器.采用双端泵浦结构,共有36个泵浦输入端.在使用其中的24个泵浦输入端,泵浦功率为1 477 W时,获得了1 008 W高功率输出,光光转换效率为68%.输出激光的中心波长为1 082 nm,半波全宽为3 nm.目前激光器输出功率受限于泵浦功率,增加泵浦源的数目有望进一步提高输出功率.%We report a high-power fiber laser in all-fiber format. The system consists of 36 pump ports, both counter and forward pump configuration are employed. In the experiment, 1 008 W fiber laser is obtained when 24 pump ports are employed with a total pump power of 1 477 W. The optical-to-optical conversion efficiency is 68％. The central wavelength of the output laser is 1 082 nm with a 3 dB bandwidth of 3 nm. Presently, the output power is limited by the pump source. It can be predicted that the laser power can be further scaled if more pump sources are employed.
