HUNDREDS OF MILLIWATTS SUPER-CONTINUUM GENERATION IN ALL-FIBER LASER

摘要

This paper reports an all-fiber super-continuum (SC)laser source with the output of 307mw in averagepower, bandwidth spanning at 500nm～1700nm andflatness below 15dB. The SC is generated in PCF(photonic crystal fiber) which is pumped by a modelockedpicoseconds fiber laser, while taking SESAM(semiconductor saturable absorber mirror) as modelockeddevice and FBG (fiber bragg grating) as cavitymirror to compose the resonator. Through optimizingthe cavity structure, an ultra-short pulse with high peakpower is achieved. And then it is coupled into PCF tolead to the super-continuum because of a series ofnonlinear effects.
