Description

Laser-wakefield acceleration experiments performed at the Hercules laser show a lowering of the self-injection threshold by circular polarized laser pulses, similar to the threshold lowering in wakfields driven in a warm plasma. In addition to the lower injection threshold, a significantly higher charge was observed for CP compared to LP for a wide range of parameters. We performed particle-in-cell simulations that support the observed experimental findings and indicate at different injection paths for CP laser pulses, which allows electrons to easier fulfill the injection condition.
