High-quality electron beams such as those used in high-energy physics experiments or as driver for FEL applications feature a low divergence and emittance. Reducing these quantities is thus a crucial step in order to allow table-top, all-optical accelerators for such a kind of applications to be developed. Here we report on a LWFA (Laser Wake-Field Acceleration) experiment aimed at studying the role of the laser polarization on setting the divergence and transverse emittance of the final electron bunch. The experimental findings were compared to PIC simulations in order to highlight the underlying physical process.
