Relativistic Transparency (RT) in laser-matter interactions occurs when light incident on an
opaque plasma becomes intense enough to drive electrons at relativistic speeds, dropping
the effective electron density of the plasma below critical so that it becomes transparent. RT
in solid-density targets using ultraintense light (> 10 20 W/cm 2) is still an active research
area, with many studies focusing on the turn-on time of the interaction. A recent pump-probe
experiment performed at the Scarlet Laser Facility has measured the turn-on and turn-off …
