8.74kW Pump-Gain Integrated Functional Laser Fiber
optical fiber communication conference(2018)
Abstract
We fabricated a (8+1)-type pump-gain integrated functional laser fiber with 8 passive pump-fibers and 1 signal-gain fiber. 8.74 kW laser output with optical-to-optical efficiency of 81% was achieved in counter-pump MOPA setup.
