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.
