Nanoshocks are tiny but powerful laser-driven shock waves that can be used to produce large-amplitude compression in molecular materials on the picosecond time scale. When coupled with ultrafast molecular spectroscopy, the molecular response to nanoshocks can be probed in detail. Simple molecular systems (anthracene crystals) are used to characterize the nanoshock pulses. Well-characterized nanoshocks are used to study complex phenomena such as shock-induced chemical reactions, shock-induced orientation of energetic solids, and shock compression of organic polymers and proteins.
纳秒级冲击波是微小但强大的激光驱动冲击波，可用于在皮秒时间尺度上对分子材料产生大幅度压缩。当与超快分子光谱相结合时，可以详细探测分子对纳秒级冲击波的响应。使用简单的分子系统（蒽晶体）来表征纳秒级冲击波脉冲。特征明确的纳秒级冲击波用于研究诸如冲击诱导的化学反应、含能固体的冲击诱导取向以及有机聚合物和蛋白质的冲击压缩等复杂现象。
