摘　　要：液相激光烧蚀方法,主要是利用激光与液态介质相互作用、产生局域高温高压非平衡过程而获得纳米材料的方法,能够有效合成常规手段无法合成的新型纳米材料。阐述了液相激光烧蚀法(包括非反应性液相激光烧蚀和反应性液相激光烧蚀)制备纳米材料的基本原理和国内外研究现状,并指出这一领域存在的主要问题与发展方向。The research progress of nanomaterials prepared by pulsed laser ablation（PLA） in liquid mediums was presented. Pulsed laser ablation in liquid mediums can produce non-equilibrium process and extreme conditions with high temperature and high pressure, leading to the formation of the novel nanostructures and some special nanomaterials which can not be obtained by other conventional methods. The principle of the synthesis of nanomaterials by PLA in liquid mediums was dwelt on. The current research status of PLA in liquid mediums including inactive and active PLA were also discussed in detail. Finally, The key problems and the development direction in this field were presented.
