A kind of simple method is presented on the measurement of average velocity of flyer driven by mini size laser using quartz gauges. In the experiments, 5.5m m thickness and 0.5~0.8mm diameter of aluminum flyer have been driven successfully by mini size YAG laser in the energy range of 100~300mJ, the highest velocity of flyer have been up to 6.6km/s, and the relationship of flyer velocity and energy density have been obtained. The process of experiments and design of quartz sensor are introduced in detail in the article, and the analysis has made on the accuracy of experiment system and experimental data. It is proved that the method is simple and reliable, and can fit well the accuracy need of experiment.
