Description

In this letter, we present a 2240 W high-brightness 1018 nm fiber laser by power combination. The system consists of seven 1018 nm ytterbium-doped fiber lasers and a homemade 7  ×  1 all-fiber power combiner. The output core diameter of the power combiner is 50 µm and the numerical aperture is 0.2. The overall transmission efficiency is about 99%. This high-power, high-brightness fiber laser can be used as a pump source in tandem pumping configurations for several kilowatts of power scaling. (letter)
