We review recent progress in the control over chemical reactions by employing tailored electric field waveforms of intense laser pulses. The sub-cycle tailoring of such waveforms permits the control of electron dynamics in molecules on sub-femtosecond timescales. We show that laser-driven electron dynamics in molecules has the potential to control chemical reactions. In the presence of strong fields, electron and nuclear motion are coupled, requiring models beyond the Born-Oppenheimer approximation for their theoretical treatment. Various mechanisms for the lightwave control of molecular reactions are described, and their relevance for the control of diatomic molecular reactions is discussed. Rapid experimental and theoretical progress is currently being made, indicating that attosecond controlled chemistry is within reach.
我们综述了利用强激光脉冲的定制电场波形来控制化学反应的最新进展。这种波形的亚周期调控使得人们能够在亚飞秒时间尺度上控制分子中的电子动力学。我们表明，分子中的激光驱动电子动力学具有控制化学反应的潜力。在强场存在下，电子和核运动相互耦合，这要求超越玻恩-奥本海默近似的理论处理模型。本文描述了各种用于控制分子反应的光波机制，并讨论了它们在控制双原子分子反应方面的相关性。目前正在取得快速的实验和理论进展，表明阿秒控制化学即将成为现实。
