Ultra-broadband supercontinuum generation using low-cost multimode pumped lasers and highly nonlinear fiber

We experimentally demonstrated an ultra-broadband supercontinuum source by using two low-cost multimode lasers, Erbium-Yerbium co-doped fiber and highly nonlinear fiber. The bandwidth of the generated broadband source is almost 1100nm, covering from 900 to 2000nm. In addition, the supercontinum source output is smooth and stable.
