我们提出了使用斯塔克啁啾快速绝热通过方法，一种技术，在该技术中，目标状态的能量扫描通过共振缓慢变化的动态斯塔克位移诱导完全的布居转移从基态1 s态的亚稳态2s的氢原子。寄生电离过程大大减少，通过使用双色激发方案。我们详细的数值计算表明，根据明智的选择脉冲参数，高达98%的人口可以发现在2s状态的过程结束时。[S1050-2947（99）51112-8]。
We propose the use of Stark chirped rapid-adiabatic-passage method, a technique in which the energy of a target state is swept through resonance by a slowly varying dynamic Stark shift to induce complete population transfer from the ground 1s state to the metastable 2s state of the hydrogen atom. Parasitic ionization processes are strongly reduced by using a two-color excitation scheme. Our detailed numerical calculations show that under judicious choice of pulse parameters, up to 98% of the population can be found in the 2s state at the end of the process. [S1050-2947(99)51112-8].
