Paper Abstract

In this paper high power Yb-doped double-clad fiber laser is presented. A Yb3+-silica fiber laser has been cladding pumped at 937 nm by a InGaAs semiconductor laser diode and operated with the slope efficiency of 73 ± 3% with respect to the incident pump power. We obtained 4 W cw-output power when working with 20-m long fiber with laser core in 7 μm diameter (cut-off wavelength - 1 μm) and pump core in 120 x 120 μm (rectangle-shaped, NA = 0.6). Yb-doping concentration has been at the level 3 - 10 • 1019 cm-3 and attenuation in laser core has been 8 - 12 dB/km. The fiber laser operated at 1084 nm.
