研究目的
Investigating the electron injection process triggered by the diffraction of a super-Gaussian laser beam in underdense plasma for laser wakefield accelerators.
研究成果
The diffraction of a super-Gaussian laser beam in underdense plasma triggers electron injection through the formation and expansion of bubbles, leading to the generation of a compact electron bunch with high charge, short duration, and low emittance. This method offers a potential tool for controlling electron bunch properties in laser wakefield accelerators.
研究不足
The method requires a challenging experimental setup for the production of pure flat-top or super-Gaussian pulses in the focus. The study is limited to specific laser and plasma parameters, and the generalizability of the findings to other conditions is not explored.
