arXiv preprint arXiv:1710.09253, 2017•arxiv.orgWe study the penetration of ultraintense circularly polarized laser pulses into a thick
subcritical plasma layer with accounting for radiation friction. We show that radiation
pressure is enhanced by radiation friction in the direction transverse to the laser pulse
propagation, and that for stronger and longer laser pulses this mechanism dominates over
the ordinary ponderomotive pressure, thus resulting in a stronger charge separation than
anticipated previously. We give estimates of the effect and compare them with the results of …
