Effect of the Stability of Intense Laser Propagation on the Quality of Electron Beams Produced By the Wakefield Acceleration

Currently, we have 100 TW (30 fs) Ti:sapphire laser system at the Advanced Photonics Research Institute of GIST. By using such a laser system, we investigate the generation of relativistic electron beams by the laser wakefield acceleration (LWFA) technique. In this paper we will present our recent experimental results.
