Abstract The interaction between ultra intensity laser and dense plasma is investigated with the use of a 1-1/2 dimensional electromagnetic, relativistic both electron and ion, particle-in-cell code, EMPAC. When laser intensity is increased, the laser front can propagate into the plasma slab even if its density is greater than the critical density and the plasma is classically opaque. The propagation velocity of the laser front is compared with the analytical model. The intensity threshold is characterized as a function of plasma density and ion-electron mass ratio. {copyright} {ital 1996 American Institute of Physics.}
