摘要: This paper presents an investigation of self-focusing a Cosh-Gaussian (ChG) laser beam and its effect on second harmonic generation in collisionless plasma. In the presence ChG carriers get redistributed from high field region to low account ponderomotive force as result which transverse density gradient is produced plasma turn generates electron-plasma wave at pump frequency. Generated interacts with incident hence harmonics. Moment theory has been used derive differential equation governing evolution spot size propagating through The so obtained solved numerically. decentered parameter, intensity yield investigated.
