1kW fiber-coupled pump-module at 976nm with 50% efficiency
We present a fiber-coupled pump-module emitting more than 1kW of mode-stripped power at 976nm from a detachable 225µm, 0.22NA fiber. The electrical-to-optical efficiency at 1kW is ~50%. Six of these pump modules attached to a (6 + 1):1 multimode combiner enable a 5-6kW, single-mode, Yb-doped fiber a...

| Zusammenfassung: | We present a fiber-coupled pump-module emitting more than 1kW of mode-stripped power at 976nm from a detachable 225µm, 0.22NA fiber. The electrical-to-optical efficiency at 1kW is ~50%. Six of these pump modules attached to a (6 + 1):1 multimode combiner enable a 5-6kW, single-mode, Yb-doped fiber amplifier. |
