Paper Abstract

In this contribution, we fabricate a kind of part-doped yb fiber with 30/400μm core/cladding diameter by Modified Chemical Vapor Deposition (MCVD) in conjunction with chelate gas deposition technique. The yb ions doping diameter is 20μm in the fiber core and the core numerical aperture (NA) is 0.061. The fiber with a 50cm coiling diameter is characterized in a master oscillator power amplifier configuration, 2.42kW laser output with an excellent beam quality factor (M2~1.32) is experimentally obtained. For our best known, it is the first time to fabricate part-doped yb fibers by MCVD with chelate gas deposition method.
