【 摘 要 】

We investigate atomic ionization in two counter-rotating circularly polarized short laser pulses by solving the three-dimensional time-dependent Schrodinger equation. Tuning the time-delay and intensity ratio between the two pulses provides us a way to steer the electron motion, in turn, the temporary profile of the atto-second pulse when the photoelectron radiatively recombines with the parent core.
