Abstract
Lasers that provide an energy encompassed in a focal volume of a few cubic wavelengths () can create relativistic intensity with maximal gradients using minimal energy. With particle-in-cell simulations we found that single 200-as pulses could be produced efficiently in a laser pulse reflection by means of deflection and phase compression caused by the coherent motion of the plasma electrons that emit these pulses. This novel technique is efficient () and can produce single attosecond pulses from the millijoule to the joule level.
