Název v původním jazyce

Optical injection into the laser wakefield accelerator by co-propagating weaker pulse.

Popis výsledku v původním jazyce

The considerable progress in the investigation of electron acceleration in laser plasmas was achieved within the last several decades. The main advantage of this concept in comparison with standard radiofrequency accelerators is in the plasma ability to sustain large accelerating gradients in order of hundreds of GV/m [1]. Currently, the most promising approach to the electron acceleration in underdense laser plasma is cavitated wakefield regime, when electrons are accelerated by the nonlinear plasma wave dragged by the ultrashort (tens of fs), ultraintense (I > 1019 W/cm2) laser pulse propagating through the gaseous target. However, the most simple and spontaneous mechanism to inject the electrons into the acceleration phase called self-injection has significant drawback, it is very difficult to control parameters of produced electron bunches due to its unstable, nonlinear nature. Therefore, various alternative mechanisms such as an injection by a density ramp, ionisation injection using a mixture of lighter and heavier gases or optical injection employing additional laser pulse(s) were proposed.
