Broadband Supercontinuum Generation Based on Ytterbium-Doped Fiber Amplifier Seeded by Self-Pulsed Amplified Spontaneous Emission Source

We report a novel method to obtain high-power near-infrared broadband supercontinuum based on amplified spontaneous emission (ASE) source. Firstly two kinds of ASE seed sources, without and with parasitic laser, are amplified to be 19.1 and 19.9 W, respectively, using a fiber amplifier. Then, comparative experiments are performed by using these two sources to pump different fibers. When using the ...
