We theoretically study the dependence of atomic excitation and ionization on the carrier envelope phase of few-cycle laser pulses in the multiphoton ionization regime. Our theoretical results for the hydrogen atom based on the solution of the 3D time-dependent Schrödinger equation show that the strong phase dependence can be seen in not only total ionization, but also bound-state population under the weak laser intensity regime.
我们从理论上研究了多光子电离 regime 中少周期激光脉冲的载波包络相位对原子激发和电离的依赖性。我们基于三维含时薛定谔方程的解对氢原子的理论结果表明，不仅在总电离中，而且在弱激光强度 regime 下的束缚态布居数中都能看到很强的相位依赖性。
