The stability of short electron bunches formed and accelerated by laser wakefield in gas jets strongly depends on parameters of pre-plasma due to poor pulse focus-ability. Instabilities provoked by light energy remained out of focus spots (halo), usually 30–50%, are shown to result in broad and spotted transverse distributions of electrons in uniform gas jets radiated by high-contrast laser pulses. Shaped pre-plasma may drastically improve pulse focus-ability with stable, well-pointed, and well-collimated electron bunches. [ABSTRACT FROM AUTHOR] |
