摘　　要：超短超强激光与液体靶相互作用时表现出许多有趣的特点 ,这明显区别于激光脉冲与固体或气体靶的相互作用情况 .文章分别介绍了激光诱发等离子体所产生的高压冲击波、激光空泡、X射线、高能超热电子以及白光 ,对它们的产生机制及其各自的显著特征进行了综合描述 .Many interesting phenomena are observed when ultrashort h igh intensity laser pulses interact with liquid targets, which are very distinct from the interactions of laser pulses with solid or gas targets. We describe th e laser induced high pressure shock waves, laser bubbles, X\|rays, ultrahot elec trons and white light that are produced in water plasmas, their characteristics, and the mechanisms of formation. The potential applications of ultrashort high intensity laser pulses interacting with different forms of liquid targets are al so discussed.
