Yb-doped F-rich aluminophosphosilicate LMA-25/400-YDF laser fiber with high efficiency and excellent stability

摘要

Yb-doped F-rich aluminophosphosilicate LMA-25/400-YDF laser fiber was fabricated by chelate precursor doping technique. 3.03 kW@1080nm laser output was achieved in an oscillator configuration with an optical-to-optical efficiency of 71.5% and shown excellent stability. © 2020 The Author(s)
