In order to study the supercontinuum generation in a photonic crystal fiber pumped at the anomalous dispersion region,a theoretical investigation with the method of split-step Fourier is presented on the nonlinear propagation and supercontinuum generation of a femtosecond laser pulse in a photonic crystal fiber.Finally,a conclusion can be drawn that the initial pulse power and initial pulse chirp have the impact on the spectral shape and band width of the supercontinuum generation at the anomalous dispersion region in a photonic crystal fiber,which provides significant reference for supercontinuum generation in photonic crystal fibers.
