Abstract
An initiator that produces an intermediate combustion step in a system for gniting solid rocket propellant with a laser beam. The initiator comprises a pyrotechnic pellet which has a concave conical surface and a breakaway/burn center section. The pellet is positioned in a container which has a window. A laser beam is directed through the window, onto the conical surface, and initiates combustion of the pellet. The container restrains the pellet from moving during combustion.
