The Hypergeometric-Gaussian laser pulse because of its donut shape profile and low divergence propagating has a unique property in industrial applications such as accelerating a hollow electron bunch. Due to the donut profile, we proposed that one can use this laser to accelerate the hollow short electron bunch. One can achieve high-energy electrons by optimizing the matching parameters of the bunch in the wake excited with a Hypergeometric-Gaussian laser pulse. Further, the effect of the pulse spot size on the emittance for different laser pulses is surveyed. We focus exclusively on them for mitigating the emittance growth with a minimized relative energy spread.
