Available in PDF, EPUB and Kindle. Book excerpt: A series of experiments with energy deposition via laser-induced optical breakdown of air, i.e., a laser spark, have been performed. These experiments have demonstrated the possibility of using a laser spark for supersonic flow control. A focused Nd:YAG laser (pulse time of 10 nanoseconds, pulse frequency of 10 Hz, and capable of energy levels up to 600 milli-Joules per pulse) was used to create the energy deposition laser spark. This laser energy deposition was then tested in quiescent air, upstream of a Mach 3.45 sphere with and without shock impingement, into shock structures within the dual solution domain, and into a compressible shear layer.
