Visible to Near-Infrared Supercontinuum Generated by Random Fiber Laser
We investigate visible to near-infrared supercontinuum generated by random fiber laser structure. Half-opened cavity random fiber laser is established, using germanium-doped fiber with several kilo-meters to provide random distributed feedback and Raman gain and ytterbium-doped fiber to supply active gain. Supercontinuum covering 600-1700 nm with 20 dB bandwidth of more than 660 nm is achieved. It shows that random fiber laser can be a novel supercontinuum source, which can be utilized to many applications where high robustness and low cost are required.
