论文摘要
原子稳定是一种通用现象，当原子与强烈和高频激光场相互作用时发生。在这项工作中，我们系统地研究了围绕激光焦点周围的浮动量（PM）力对原子稳定的影响。我们表明，PM力可以诱导隧道，甚至对原子原子的电离过度电离。这种影响可能超重，在中等激光强度下，典型的多光子离子化。我们的工作强调了改进原子稳定治疗的重要性，包括PM力的影响。
Atomic stabilization is a universal phenomenon that occurs when atoms interact with intense and high-frequency laser fields. In this work, we systematically study the influence of the ponderomotive (PM) force, present around the laser focus, on atomic stabilization. We show that the PM force could induce tunneling and even over-barrier ionization to the otherwise stabilized atoms. Such effect may overweight the typical multiphoton ionization under moderate laser intensities. Our work highlights the importance of an improved treatment of atomic stabilization that includes the influence of the PM force.
