ABSTRACT:
Hollow shell laser fusion targets, such as glass microballoons, are filled with gases of the type which do not permeate through the wall of the balloon. A hole is laser-drilled in the balloon, a plug is placed over the hole and gas is introduced into the balloon through the loosely plugged hole. Thereafter the plug is melted to form a seal over the hole, entrapping the gas within the target. The plug is, for example, a polymer such as highly crystalline polystyrene, or glass.
