Optical injection into the laser wakefield accelerator by co-propagating weaker pulse
Original language description
This contribution proposes the new scheme of the electron injection into the laser wakefield accelerator using a pair of mutually delayed laser pulses. The ponderomotive force associated with the preceding weak injection prepulse forms an ion cavity with the regions of higher electron densities on its borders. The size of the bubble and the delay between pulses is designed with the intention to place these regions to the collection volume from where the electrons are self-injected into the accelerating wakefield induced by delayed stronger driver pulse. The process is studied via three dimensional particle-in-cell simulations. The advantages of our approach in comparison to the pure self-injection are similar as by other optical injection schemes, i.e. its improved stability and controllability. Furthermore, the qualitative asset of our mechanism is its easier feasibility in the laboratory since the delay between pulses is tunable, contrary to the difficult spatial and temporal adjustment of colliding laser beams.
