The dynamic behavior of laser-driven flyers has been studied using high-speed streak imaging in combination with stop motion microphotography. With very thin targets, melting and plasma penetration of the flyer material occur in rapid sequence. The time delay from onset of motion to flyer breakup increases with flyer thickness and decreasing incident energy. Materials examined include pure aluminum and composite samples containing an insulating layer of Al{sub 2}O{sub 3}. While flyer breakup is observed in both cases, the Al{sub 2}O{sub 3} barrier significantly delays the deleterious effects of deep thermal diffusion. {copyright} {ital 1996 American Institute of Physics.}
