Abstract

Restricting attention to circularly-polarized pulses, we undertake a systematic comparison of 1D-3V PIC-simulation results to predictions of a cold-fluid model for the threshold of relativistic self induced transparency in overdense plasmas. We find that kinetic effects, such as longitudinal electron heating, dominate the process at high laser intensity, causing electrons to escape into the vacuum and leading to an increase of the effective critical density compared to the predictions of the cold-fluid model. We interpret our results through a dynamical systems' study of single electron phase space at the plasma-vacuum interface.
