We found optimum pulse length to excite strong wakefields by investigation of electric fields and density variation, which caused by propagation of intense relativistic laser pulse through underdense plasma as well as average kinetic energy of electrons, for lasers with different pulse lengths.   %U https://ijpr.iut.ac.ir/article_1657_a00e8073c2020d617e094628c2c3a15d.pdf
