Collimated particle acceleration driven by intense vortex laser

Fundamental Physics at Extreme Light > Particle Acceleration-II

With the development of advance laser technologies, an LG laser has the potential to be extended to the relativistic regime. Now the highest intensity of the LG laser can reach up to 6.3×10¹⁹W/cm² by using the reflected phase plate on the petawatt laser facility in experiments. The relativistic LG laser is expected to open new doors for particle manipulation in relativistic interacting regime, because the hollow intensity distribution of the LG laser may generate a transverse potential well on the beam axis and provide a confining force to collimate matters. It is believed that particles can be accelerated in a concentrated manner in a new regime, to overcome some of the drawbacks of Gaussian-laser driven particle acceleration to a certain extent.
