AbstractLaser absorption in the interaction between ultra-intense femtosecond laser and solid density plasma is studied theoretically here in the intensity range Iλ2≃1014-1016Wcm-2μm2documentclass[12pt]{minimal} usepackage{amsmath} usepackage{wasysym} usepackage{amsfonts} usepackage{amssymb} usepackage{amsbsy} usepackage{mathrsfs} usepackage{upgreek} setlength{oddsidemargin}{-69pt} egin{document}$$ I{lambda^2} simeq 10^{14}{-}10^{16};{ ext{W}};{{ ext{cm}}^{-2}} ;upmu{{ ext{m}}^{2}} $$end{document}. The collisionless effect is found to be significant when the incident laser intensity is less than […]
