We have developed a high-speed laser stroboscopic videography technique, in which a high-speed vido camera is combined with a high repetition rate, short pulse laser. We are studying on dynamics of laser ablation in liquid over wide time-scale, from ns to ms, using this technique. In this paper, we present two examples, laser peening under liquid and nano-particle production by laser ablation in liquid, to describe the system with some new findings on these processes.
