We demonstrate the blue light generated in high-△ photonic crystal fibers(PCFs).A femtosecond Yb-doped fiber laser,operating at 1039nm,is used to pump a GeO2-doped PCF in the largely anomalous group velocity dispersion(GVD) region.The emitted radiation covers 418.6-544.6 nm with 5 dB flatness.The calculated result indicates that the cross phase module(XPM) effect induced by higher-mode soliton makes a contribution to the blue component generation.
