【Abstract】 Two pump method designs of the high power fiber laser with the fiber combiner are reported. The pump method based on the(6+1)×1 fiber combiner,(6+1)×1 fiber combiner and 7×1 fiber combiner cascaded pump method is studied respectively. With the latter, 806 W power is outputted. The coupling efficiency is 90.6% and the max backward power is 37 m W. It is founded that the(6+1)×1 fiber combiner and 7×1fiber combiner cascaded pump method has high coupling efficiency, low backward power and meet the 500 W fiber laser design requirement.更多还原
