摘　　要：A higfi-power all-fiber supercontinuum （SC） laser source based on germania-core fiber （GCF） was presented. The lesser absorption loss of GCF than silica fiber beyond 2.0 μm makes GCF more suitable for extending the SC spectrum to the long wavelength side. In this work, the GCF-based SC laser had a maximum power of 30.1 W, together with a 10 dB spectral bandwidth of 〉 1000 um spanning from 1.95 to 3.0 μm. To the best of our knowledge, this is the highest output power level ever reported for a GCF-based SC laser as well as a 2-3 μm SC laser.A high-power all-fiber supercontinuum(SC) laser source based on germania-core fiber(GCF) was presented.
