• 論文の詳細を見る

• The dynamics of a charged particle interacting with a short laser pulse propagating in a plasma is studied analytically and numerically. It is shown that the dynamics of a positive particle is quite different from that of a negative one of the same absolute charge-mass ratio, except for the case of ultrashort pulses (L≪λ_p). A positive particle may be accelerated to very high energy even when both the pulse intensity and the particle injection energy are low. The dependence of the particle dynamics on the pulse length is studied in detail.
