| 中文摘要 | photoionization of hydrogen atoms in few-cycle laser pulses is studied numerically. the total ionization probability, the. instantaneous ionization probability; and the partial ionization probabilities in a pair of opposite directions are obtained. the partial ionization probabilities are not always equal to each other which is termed as inversion asymmetry. the variation of asymmetry degree with the ce phase, the pulse duration and the pulse intensity is studied. it is found that the pulse intensity affects the asymmetry degree in many aspects. firstly, the asymmetry is more distinct at higher intensities than that at lower intensities when the pulse duration exceeds 4 cycles; secondly, the maximal asymmetry in lower intensities varies with the ce phase visibly while at higher intensities riot; thirdly, the partial ionization probabilities equal to each other for some special ce phases. for lower pulse intensities, the corresponding value of ce phase is always 0.5 pi and 1.5 pi, while for higher pulse intensities, the corresponding value varies with the pulse intensity. similar phenomena were observed in a recent experiment using few-cycle radio-frequency (rf) pulses. |
