Relativistic High Harmonics Generation in Underdense Plasma Produced by a Super Intense Femtosecond Laser Pulse
A high intensity laser incident on a vacuum-plasma interface, insert an Intensive electromagnetic force on electrons and charged particles. Relativistic charged particle movements lead to the high order harmonics generation of the incident wave. Efficiency of high harmonics increases with the intensity laser incident, So that the non-relativistic velocities of the particles vary to the relativistic velocities. Efficiency of high harmonics increases with the intensity laser incident. In previous works that has done in this field the researcher have reported-odd harmonics generated in direction of propagation of laser incident and even harmonics generated in normal direction of propagation of laser incident but in experimental results we can observe all harmonics in direction of propagation. The set of equations that are presented in other papers had been solved for SHG and THG while we have been presenting a set of equations and numerical analytic program do for any harmonics.
