研究目的
Investigating the self-focusing of laser beams in collisional plasma with periodical density ripple.
研究成果
Under the influence of collision nonlinear effect, laser presents stable self-focusing, self-defocusing, and oscillational self-focusing in plasma with periodical density ripple. Selecting a suitable periodic plasma system is advantageous for separating self-defocusing and oscillational self-focusing, and for the formation of a more stable collisional self-focusing.
研究不足
The study focuses on theoretical analysis and numerical calculations, lacking experimental validation.
