Abstract

In this paper a high-power Nd-doped double-clad fiber laser is presented. We obtained 10 W cw-output power from 20 m long fiber with laser core in 12 μm diameter (NA = 0.12) and pump core in 400 μm diameter (D-shaped, NA = 0.38). Nd-doping concentration has been at 1300 ppm level and attenuation in the laser core has been less than 10 dB/km (for λ = 1100 nm). High power diode laser module operating at λ = 808 nm has been used as a pump unit. This pump ensured 30 W cw output power. As a result, we have built a coherent source of radiation generating 10 W cw output power with 63 percent slope efficiency.
