| contents | This investigation deals with enhanced plasma wakefield amplitude generated using two co-propagating laser pulses in homogeneous plasma. The configuration consists of a seed pulse followed by a trailing pulse, both linearly polarized and sharing identical laser parameters. The enhancement in wakefield amplitude corresponding to fixed spatial separation is optimized for various pulse widths and intensities of the seed and trailing lasers. Analytical modelling and particle-in-cell simulations reveal that the maximum amplification in wakefield amplitude is obtained when spatial separation equals the plasma wavelength (λ_p). The spatial intervals between laser pulses critically influence the wakefield amplification. These findings confirm that the two co-propagating lasers scheme provides a promising route toward stronger plasma wakefield excitation, potentially important for various applications. |
