Influence of longitudinal chromatism on vacuum acceleration by intense radially polarized laser beams
Abstract:
We report with single-particle simulations that longitudinal chromatism, a commonly occurring spatio-temporal coupling in ultrashort laser pulses, can have a significant influence in the longitudinal acceleration of electrons via high-power, tightly-focused, and radially polarized laser beams. This effect can be advantageous, and even more so when combined with small values of temporal chirp. However, the effect can also be highly destructive when the magnitude and sign of the longitudinal chromatism is not ideal, even at very small magnitudes. This motivates the characterization and understanding of the driving laser pulses and further study of the influence of similar low-order spatial-temporal couplings on such acceleration.

Based on geometry, beams can be straight, tapered, or curved. Straight beams are the most common type and have a constant cross-section throughout their length. Tapered beams, on the other hand, have a varying cross-section along...
