The influence of pulse width,phase,and Coulomb potential on the holographic interference structure in the photoelectron momentum distribution from Xe atoms is investigated using the quantum Monte Carlo method under a linearly polarized laser pulse.The results show that the interference structure gradually appears with the increase of pulse width,and a complete spider-like holographic interference structure is formed when the pulse width is an optical cycle.The spider-like structure is sensitive to the phase,and the holographic interference fringes can disappear and reappear by adjusting the phase,and the photoelectron momentum distribution with phase difference π is inversion symmetry.In addition,it is proved that the Coulomb potential mainly affects the formation of the holographic interference structure. When the Coulomb potential is not considered,the holographic interference structure disappears and only the double-slit interference structure appears.This result provides an effective means for experimentally regulating interference fringes,which is beneficial for extracting ultrafast electron dynamics information.
