Abstract Relativistic self-focusing causes a shrinking of laser beams in high density plasmas down to one wavelength diameter within a penetration depth approximately equal to the diameter of the initial beam in vacuum before the plasma interaction. Values of electron densities near cut-off cause a swelling and an increase of the actual wavelength in the focused volume. Both mechanisms are evaluated for the relevant laser intensities below and above the relativistic threshold. The result of McCall et al., a wavelength independence of electron oscillation energies, is derived from short-range self-focusing; in addition, the illustration of GeV ion generation, with magnitudes linearly increasing with respect to the ion chargeZ I and laser intensityI, is also made.
