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. |
