Abstract

OASYS Technology has an ongoing program to design and fabricate high-energy laser detonation devices for Los Alamos National Laboratories. The purpose of this program is to demonstrate the feasibility of detonating high explosive (HE) by focusing the energy from a fiber-coupled, high energy laser onto a metallized window surface. A high explosive package integrated with the metallized window keeps the high explosive material isolated from the ambient environment until activated by the vaporization of the window metal film by the laser. The package constraints for these designs require a right angle turn that must be achieved by reflection, since the minimum bend radius of the fiber is substantially larger than the desired package size. Four optical designs were proposed and fabricated to compare survival and detonation efficiency. This paper will discuss the design requirements, fabricated designs, test methods and results, and conclusions.
