Abstract

In this report, two kinds of ytterbium doped double-cladding fibers (YDFs) are fabricated by Modified Chemical Vapor Deposition (MCVD) in conjunction with solution doping technology. The fiber core contains SiO₂, Yb₂O₃, Al₂O₃, and P₂O₅. After testing in a master oscillator power amplifier (MOPA) configuration, the maximum laser output power of 25μm-core YDF and 30μm-core YDF reaches 3kW and 10kW. In addition, nonlinear effects are not found in the experiment. The experiment results experience that solution doping is a promising technology to fabricate high power laser fiber.
