摘要：

激光激发纳米尺度的原子和分子团簇为探索和控制超快多粒子动力学提供了各种机会。而弱激光场允许分析光电离，激发态弛豫，和这些有限的量子系统的结构修改，大振幅集体电子运动和库仑爆炸可以诱导与强激光脉冲。本文综述了激光与团簇相互作用中的主要现象，重点是非线性光学激发，并根据目前的理解讨论了基本过程。简要概述了激光驱动团簇动力学的基本性质和激发机制。然后，在理论和实验方法的偏移后，单光子和多光子激发的结果进行了审查，重点是从时间和角度分辨光电发射的签名。这篇评论的一个关键问题是从暴露于强场的团簇中产生的广谱现象，其中与激光脉冲的相互作用产生了短寿命和密集的纳米等离子体。技术发展的影响包括离子，电子和辐射脉冲的控制产生，将与相应的例子一起解决。最后，展望了激光团簇研究的未来，以及在实验和理论上面临的挑战。

英文摘要：

Laser excitation of nanometer-sized atomic and molecular clusters offers various opportunities to explore and control ultrafast many-particle dynamics. Whereas weak laser fields allow the analysis of photoionization, excited-state relaxation, and structural modifications on these finite quantum systems, large-amplitude collective electron motion and Coulomb explosion can be induced with intense laser pulses. This review provides an overview of key phenomena arising from laser-cluster interactions with focus on nonlinear optical excitations and discusses the underlying processes according to the current understanding. A brief general survey covers basic cluster properties and excitation mechanisms relevant for laser-driven cluster dynamics. Then, after an excursion in theoretical and experimental methods, results for single- and multiphoton excitations are reviewed with emphasis on signatures from time- and angular resolved photoemission. A key issue of this review is the broad spectrum of phenomena arising from clusters exposed to strong fields, where the interaction with the laser pulse creates short-lived and dense nanoplasmas. The implications for technical developments include the controlled generation of ion, electron, and radiation pulses, as will be addressed along with corresponding examples. Finally, future prospects of laser-cluster research as well as experimental and theoretical challenges are discussed.
