We utilise a combined laser micromachining technology to manufacture complex gas nozzles to tailor the plasma target for laser wakefield accelerators. A two-stage supersonic nozzle was optimised for the injection and acceleration of electrons using a Bessel-Gauss driving beam. The first nozzle is used for the ionisation injection of electrons. The nozzle is for the LWFA acceleration of electrons.
