Abstract

A mechanical impulse generated from laser-illuminated targets is investigated. Solid material, liquid-droplet and gas-puff targets are compared. A free expansion of explosion products and a forced trajectory change using a solid deflector are studied. A momentum transfer into the deflector was measured. The optimal combination of the target and deflector material is also examined. The deflector can be used in a hybrid laser propulsion system.
