Abstract

We demonstrate an all-fiber SC laser source based on a 0.9 m-long 94 mol.% GCF which was pumped by a Single-Mode (SM) TDFA-based 1.9~2.7 μm laser source. A 2.59 W flat SC spectrum with coverage of 1.9~3.5 μm were achieved under a seed pulse repetition rate of 600 kHz and a pulse duration of 1 ns. The 3 dB bandwidth was 1210 nm ranging from 1970 to 3180 nm and the 10 dB bandwidth was 1380 nm ranging from 1920 to 3300 nm.
