Two laser beams with different divergences are obtained using 300 mm and 1500 mm lens. The ionic fragments distributions of the two laser beams are measured by a time-of-flight mass spectrometer. The results show that with the increasing divergence of laser beam, the fragmentation degree of C60, the yield of delayed ionization of C60 and the total yield of the ionic fragment C+n(n＜25) have steeper change depending on fluences. In addition, the yield of delayed ionization has a larger proportion than direct ionization. The experimental results are in reasonable agreement with the latest prediction by multiple photon absorption theory.
