Some Fundamental Concepts of Femtosecond Laser Filamentation

The fundamental physical concepts underlying filamentation are discussed. These include sliceby- slice self-focusing, intensity clamping, back ground reservoir and self-compression of the pulse during propagation.

PLASMA TORCH POWER CONTROL FOR SCRAMJET APPLICATION

Plasma torches have proven reliable methods of ignition and flame-holding for supersonic combustion applications. The Hy-V Scramjet Flight Experiment plans to use an 800W plasma torch for ignition of hydrogen
