主　　题：femtosecond pulse ultrafast measurement supercontinuum 

摘      要：The blue-shifted supercontinuum generation in a photonic crystal fiber pumped by high peak power femtosecond pulses with a wavelength located in the anomalous dispersion region is investigated experimentally and *** formation of a blue-shifted enhanced supercontinuum due to the pulse collapse is *** process of the pulse collapse is measured by using the grating-eliminated no-nonsense observation of ultrafast incident laser light e-fields technique（GRENOUILLE）.Numerical simulations in spectral and temporal domains are *** data from the numerical simulations are in good agreement with the experimental *** experimental results and numerical simulations show that pulse collapse is the determining factor in the generation of a blue-shifted supercontinuum.
