我们开发了一种方法，使用一系列飞秒激光脉冲，以分段方式在量子态之间执行完整的布居转移。该方法可以应用于一个大类的问题，因为它受益于由飞秒脉冲提供的高峰功率和大的光谱带宽。人口转移的程度是强大的绝对和相对强度，持续时间和脉冲的时间顺序的广泛变化。该方法详细研究了原子钠的分段绝热布居转移，以及诱导拉姆齐型干扰，证明。
We develop a method of executing complete population transfers between quantum states in a piecewise manner using a series of femtosecond laser pulses. The method can be applied to a large class of problems as it benefits from the high peak powers and large spectral bandwidths afforded by femtosecond pulses. The degree of population transfer is robust to a wide variation in the absolute and relative intensities, durations, and time ordering of the pulses. The method is studied in detail for atomic sodium where piecewise adiabatic population transfer, as well as the induction of Ramsey-type interferences, is demonstrated.
