摘要

The one-photon ionization and tunneling ionization of H2 exposed to strong XUV and infrared laser pulses are studied by numerically simulating the four-dimensional time-dependent Schrödinger equation, which includes two-electron dynamics for arbitrary angle between the molecular axis and the laser polarization direction. In the one-photon single ionization of H2, one electron escapes fast and the other bound electron is not disturbed but remains in coherent superposition of two electronic states of

H_{2}^{+}

. In another case, under the irradiation of strong infrared laser pulses, one electron tunnels through the laser-dressed Coulomb barrier, and the other bound electron has enough time to adapt to the potential of

H_{2}^{+}

and thus is prone to transfer to the ground electronic state of

H_{2}^{+}

. In the intermediate regime, between the one photon and tunneling regimes, this electron-electron correlation depends strongly on the laser frequency, laser intensity and on the angle between laser polarization and the molecular axis.

H2+。在另一种情况下，在强红外激光脉冲的照射下，一个电子隧穿经过激光修饰的库仑势垒，而另一个被束缚的电子有足够的时间适应H2+，因此易于转移到H2+。在中间状态下，在一个光子和隧穿状态之间，这种电子电子相关性在很大程度上取决于激光频率，激光强度以及激光偏振与分子轴之间的夹角。
