The laser-driven flyer(LDF) technique is widely used to simulate micro meteoroids and orbital debris(M/OD) with respect to their hypervelocity impacting effects.The flyer velocity is one of the key parameters of LDF and it is influenced by many factors.This paper analyzes the relationships between the flyer velocity and the laser energy, the width of laser pulse, the diameter of laser focal spot, and the flyer thickness based on Lawrence-Gurney model.Higher velocity flyer is obtained by using thinner target or smaller laser focal spot.At the same time, long pulse-high energy or short pulse-low energy laser are preferred in those experiments.These relations may help to obtain high velocity flyers in the LDF experiment.
