摘要: Abstract A theoretical model is purposed which explains propagation of the cosh-Gaussian laser beam in plasma with exponential density transition. Also influence linear absorption on self-focusing taken into account and it may be helpful achieving enhanced beam. The nonlinearity arises because relativistic motion electrons, considered for penetration plasma. By considering expression dielectric function, we have set up differential equation width parameter. Further, effect decentred parameter studied results stronger Stronger also noticed increased frequency.
