Abstract
An all-fiber structured supercontinuum source based on chirped pulse amplification (CPA) technology and the use of nonlinear photonic crystal fiber was constructed. By experimentally varying fiber stretcher length in CPA laser source, we can change the spectral coverage and therefore the percentage of visible light in the produced supercontinuum at output of nonlinear photonic crystal fiber, while the average supercontinuum power always keeps at watts of level. The all-fiber structured feature and the capability of changing supercontinuum spectral coverage make this CPA system a promising implement for different applications that require different broad band spectrum.
