The generation of high-current ({gt}kA), relativistic electron beams from the wave breaking of plasma waves generated by a highly nonlinear interaction between Raman scattering, self-heating, and self-focusing of high-power ({gt}5 TW), short-pulse ({lt}1 ps) lasers is examined in detail using a fully explicit particle-in-cell model. The resulting beams have a continuous energy spread with a maximum energy exceeding simple dephasing estimates. For a 5J laser, a total of 2{times}10{sup 11} electrons are accelerated, but 2{times}10{sup 8} electrons are at 50{plus_minus}1 MeV with a normalized emittance of 13{pi} mm mrad. {copyright} {ital 1997} {ital The American Physical Society}
