This is probably enough to ionize Rydberg Hydrogen, depending on the exact level. The plasma will at least initially be dense, if the initial hydrogen is dense, simply because it doesn't have time to "explode".
Quote from https://phys.org/news/2015-11-discovery-enable-portable-particle.html "If you increase the plasma density enough, even a pipsqueak of a laser pulse can generate strong relativistic effects," Milchberg added. Note that they were using plasma densities 20 greater than normal. However Holmlid is talking about densities a million times greater than normal IIRC. I suspect this means that a deliberately "chirped" laser may not be needed. If the accelerated protons attain GeV energies, then they are quite capable of creating a whole zoo of charged particles.
