Nonlinear Interaction of q-Gaussian Laser Beams with Plasma Channels

Nonlinear phenomena of laser beams in plasma channel created by using Ignitor-Heater technique. Optical Guiding: Enhancement of the propagation distance of laser beams through plasma for efficient laser plasma coupling. Phase Modulation: Gouy phase shift of the laser beam as a result of self focusing. Harmonic Generation: Frequency up conversion of the laser beam that may produce coherent X-ray emissions beneficial for medical diagnostics.
