Abstract

Utilizing a pulsed beam of a Nd:YAG laser, hole burning through the opaque cloud of products formed following the detonation of lead azide is demonstrated. The characteristics of the hole and of the expanding cloud are monitored in real time by a HeNe beam and by high-speed framing photography. The hole is carried with the cloud and propagates at a constant velocity of 0.5-2.8 km/s, depending on the time and location of burning. The hole burning is a result of eliminating solid particles from the cloud. The application of a laser to burn a hole in the detonation products from a solid explosive is demonstrated for the first time. This technique may serve as a method for flow visualization in an aerosol medium.
