Description
Structured carbon-nanotube targets can be used as a medium for accelerating self-injected electrons within a laser-driven wakefield bubble, analogous to blowout laser wakefield acceleration (LWFA) in gaseous plasmas. A previous numerical work demonstrated this behavior using a three-cycle, 800 nm, circularly polarized laser pulse with a peak power of 35.5 TW. In this study, we compare electron beam properties for linearly and circularly polarized pulses interacting with a same target. We find that, in both cases, the analyzed beam parameters exhibit similar values, with only small discrepancies during the acceleration process inside the target and remaining nearly identical after extraction. Total charge, median energy, emittance, and divergence remain comparable for both polarizations, with only the energy spread showing an appreciable difference of approximately 8%.
