Recent progress on laser acceleration

Recently, there has been a great interest in ultrahigh field particle acceleration driven by ultraintense laser pulses in plasmas. Although particle acceleration by laser fields has been proposed since the beginning of the laser evolution, there has been tremendous progress in recent years. The laser-driven particle acceleration concepts are reviewed on the physics mechanism. In particular, the electron acceleration by the laser wakefield in plasmas is illustrated by recent experimental results. Recent progress on the laser wakefield accelerators (LWFA) with the plasma waveguiding is presented as a capillary-guided LWFA for GeV particle acceleration.
