This paper discusses some aspect of the experimental effort in high field science (up to 10²² W/cm²) done with the high peak power (>200TW) laser system at the Advanced Laser Light Source facility (ALLS). A maximum intensity of 10²² W/cm² has been achieved on target. The present experiments explore the acceleration of electrons directly by the laser field (DLFA) in the transition between the relativistic and ultra-relatisitic regimes. Electrons are accelerated to multi-MeV energies using radially (TM₀₁) and azimuthally (TE₀₁) polarized modes and the contribution of various acceleration processes is briefly discussed.
