A monolithic visible supercontinuum source with a record average output power of 204 W and a spectrum ranging from 580 nm to beyond 2400 nm has been achieved in a piece of standard telecom graded-index multimode fiber by designing the pumping system. The influence of the fiber length on the geometrical parameter instability effect has been analyzed for the first time, comparing the SC spectral region dominated by the GPI effect under different fiber lengths. This work could lead to robust, cost-effective, and high-power visible SC sources.
A monolithic visible supercontinuum (SC) source with a record average output power of 204 W and a spectrum ranging from 580 nm to beyond 2400 nm is achieved in a piece of standard telecom graded-index multimode fiber (GRIN MMF) by designing the pumping system. The influence of the GRIN MMF length on the geometrical parameter instability (GPI) effect is analyzed for the first time, to the best of our knowledge, by comparing the SC spectral region dominated by the GPI effect under different fiber lengths. Our work could pave the way for robust, cost-effective, and high-power visible SC sources.
