摘　　要：本文研究了光滑激光脉冲作用下包含高阶离化的强场自电离过程,导出了其中的基本方程,得到了基态布居和光电子谱的一系列解析表达式。讨论了指数增长脉冲作用时的具体结果,发现高能谱比低能谱更能呈现出光电子谱在脉冲光作用下特有的多峰分裂。This paper presents a study of strong-field autoionization induced by strong smooth laser pulses. Basic equations and a series of analytical expressions are derived. Explicit results are discussed for the autoionization induced by an exponentially growing laser pulse. It is shown that the multipeak splitting is more evident in the high-energy photoelectron spectrum than in the low-energy spectrum.
