摘要

The generation of supercontinuum[SC]often requires ultrashort pulsed lasers with high peak power and gain media with large nonlinear coefficients,such as a long piece of fiber or photonic crystal fiber.In this Letter,we propose and dem-onstrate that high-power SC can be generated through a simple narrow-bandwidth fiber Bragg gratings[FBGs]-based laser cavity without any modulation,based on the mechanism of intense nonlinear effects induced by the inherent self-pulsation generated inside the cavity.In the experiment,an ～80 W SC laser with the spectrum range from ＜ 600 nm to 1600 nm was achieved.To the best of our knowledge,this is the first report about SC generation through a simple fiber laser cavity.This work enriches the research content of SC and provides a cost-effective method for high-power SC lasers.
