Abstract

The progress in the ultra‐intense laser technologies continues to open up new fields of physics. The laser accelerator development enters a new matured stage at which it becomes possible to manipulate in a controllable way the parameters of accelerated charged particle beams. In the electron acceleration the particle injection by breaking wake waves left by the laser pulse in underdense plasmas or by interacting two laser pulses results in the quasi‐mono‐energetic beam production. When the ions are accelerated during the laser‐matter interaction the tailored multi‐layer foil targets provide conditions for the high quality proton beam generation. When the laser pulse radiation pressure is dominant, the laser energy is transformed efficiently into the energy of fast ions. Ultrahigh intense electromagnetic fields can be generated due to the laser pulse compression, carrier frequency upshifting, and focusing by a counterpropagating breaking plasma wave, relativistic flying mirrors.
