研究了强相干光场作用下原子的弛豫过程。与流行的做法相反，我们发现，布洛赫方程不适用时，所施加的字段是足够强的饱和过渡。与场同相的激发极化分量比异相分量的寿命长。一个重要的结果是，如果脉冲幅度足够大，则用于原子能级绝热反转的脉冲持续时间相对于原子的横向弛豫时间不需要很短。
Atomic relaxation in the presence of a strong coherent optical field is examined. Contrary to popular practice, we find that the Bloch equations do not apply when the applied field is strong enough to saturate the transition. The component of the induced polarization in phase with the field lives longer than the out-of-phase component. One important consequence is that pulse durations for adiabatic inversion of atomic levels need not be short relative to the transverse relaxation time of the atom if the pulse amplitude is sufficiently large.
