Abstract :
This paper presents a brief discussion of ultra-short laser pulse propagation and laser wakefield acceleration in plasma channels. An envelope equation for the perturbed laser beam radius is given, including finite-pulse length and nonlinear effects. The angular distribution of electrons generated by the process of laser ionization and ponderomotive acceleration (LIPA) is also discussed. An example of laser wakefield acceleration to electron energies greater than 1.2 GeV in a preformed plasma channel is described
