  ABSTRACT: The relativistic self-focusing of HChG beam in the plasma has been investigated theoretically using WKB and paraxial ray approximation for mode indices 0, 1 and 2 for different values of pulse amplitude, normalized plasma density and decentred parameter. The plot between beam width parameter f and the normalized length ξ for different value of normalized density has been reported and indicates the enhancement of the self-focusing phenomena of the laser beams in the plasmas. Also the focusing and defocusing of HChG beam in the plasma having dependency on decentred parameter and frequency of incident laser beam is reported.
