摘要
We perform a theoretical investigation on the control of photoelectron holography with shaped intense ultrashort laser pulses. By adjusting the pi phase-flip position in the frequency domain, the shape of the time-dependent envelope of the input laser electric field changes from Gaussian to trapezoidal and finally to double-peak pulse. The photoelectron momentum spectra for different pulse shapes are calculated by both three-dimensional time-dependent Schrodinger equation (TDSE) method and Quantum-trajectory Monte Carlo (QTMC) model, and good agreement is achieved between results calculated by the two methods. Interference pattern in photoelectron holography exhibits a strong dependence on the shape of the electric field. Analysis shows that adjacent and nonadjacent intercycle interference as well as intracycle interference are all effectively regulated by the shaped pulse.
