【 摘 要 】

A new approach is identified that can generate highly coherent hole wave packets with multi-cycle strong-field pulses and stands in contrast to the usual idea of making the ionizing pulse as short as possible. The effect is demonstrated in atomic xenon with a spin-orbit wave packet involving the 5p-13/2and 5p-11/2ionic states. Tuning the driving frequency to an even fraction of the hole oscillation frequency ensures the creation of highly coherent holes.
