The evolution of molecular wave packet in superstrong laser fields

Summary In this note wc numerically simulate the wave packet evolution of H2 + in superstrong laser fields with the multiple electronic-states model. The result is that the evolution process of H2 + wave packet is mainly determined by the laser frequency. For the high-frequency fields H2 + wave packet extends out of the interaction region step by step. However, the H2 + wave packet is quickly dissociated in low-frequency fields. In addition, the molecular stabilization effect can be characterized at the intensity of 8 × 1015 W/cm2 for the low-frequency field ω1.
