Laser-matter interactions enter a new area with the advent of ultraintense laser beams in the 1018 - 1019 W/cm2 range. Such experiments are now within reach since new short-pulse laser technology has recently made possible the production of laser sources with output power at multiterawatt levels with picosecond or subpicosecond pulses. These experiments should yield a significant increase in the knowledge of fundamental aspects of interactions at this relativistic regime. The two main experimental approaches are based on excimer lasers, especially KrF lasers at 248 nm and chirped pulse amplification (CPA) in broadband solid-state materials such as Nd-glass amplifiers, followed by temporal compression down to the one picosecond regime /1/. The latter approach at 1.06 micrometers was chosen because most of the new physical effects expected at about 1019 W/cm2 are governed by the parameter I(lambda) 2, where I is the focused intensity and (lambda) the laser wavelength.
