Electron Density Measurement of Laser Supported Detonation Waves

Description

In Repetitive Pulse laser propulsion, a laser supported detonation (LSD) regime is very important for efficient energy conversion in a vehicle. Then its dependency on operational parameters should be predicted for the vehicle design and its feasibility studies. Electron density distribution behind a shock wave has been measured by means of Mach-Zehnder interferometry. As a result, timing of LSD termination was determined from the history of plasma density discontinuity and the LSD threshold was re-evaluated.
