Paper Abstract

Accelerators at the frontier of high energy physics (-106 MeV for protons, -105 MeV for electrons) have reached enormous proportions (tens of kilometers). The use of lasers to accelerate particles is attractive because of the extremely large electric fields they can produce (up to 107 MeV/m). If such fields could be effectively coupled to charged particles ultra-high energies could be attained in a short distance, thereby miniaturizing a high energy accelerator. This paper reviews the status of several laser-driven particle acceler-ator schemes. These include (a) the inverse-free-electron-laser (IFEL), (b) laser and free-electron-laser driven microstructures such as minaturized linacs and gratings, and (c) laser-driven plasma space charge waves. Longitudinal accelerating fields of order 1 GeV/m have already been demonstrated in a recent laser accelerator experiment. New roles for lasers in particle acceleration continuously emerge. Examples of these include laser induced final focusing of a very high energy particle beam and laser-driven photocathodes for improved beam quality. Several novel accelerating schemes make use of picosecond laser pulses as fast switches to convert stored energy into high peak electric fields.
