An injector and accelerator is analyzed that uses three collinear laser pulses in a plasma an intense pump pulse, which generates a large wakefield ({ge}15GV/m), and two counterpropagating injection pulses. When the injection pulses collide, a slow phase velocity ponderomotive wave is generated that injects electrons into the fast wakefield for acceleration. For injection pulse intensities of 5{times}10{sup 16}W/cm{sup 2} and wakefield amplitudes of {delta}n/n{approx_equal}0.6, the production of ultrashort ({le}20fs) relativistic electron bunches with energy spreads {le}20{percent} and densities {ge}10{sup 17}cm{sup {minus}3} appears possible. {copyright} {ital 1997 American Institute of Physics.}
