As a high technology, laser-driven flyer plate widely applies on basic theoretical research and engineering. The energy relationship between laser and flyer plate is always one of hot spot of the research. According to detonation wave theory supported by laser induced, we analyze time-space distribution of detonation-wave pressure on flyer plate, and deduct the analytic equation of kinetic energy coupling efficient of laser-driven flyer plate. Finally, supposed aluminum flyer plate as an example, we mainly analyze the relation among laser parameters (such as power density, pulse width), flyer construction parameters (such as flyer thickness, diameter) and kinetic energy coupling efficient of flyer plate. The computational results indicate that the kinetic energy coupling efficient of flyer plate increases with pulse width and flyer plate diameter, whereas decreases with power density and flyer plate thickness.
