Abstract
Using particle-in-cell simulations we show that a steady, megagauss magneti c field can be generated due to ionization dephasing in the interaction of an ultrashort laser pulse with a dielectric target. The magnetic field ampl itude is limited by the screening of the laser-produced plasma and depends upon the ionization threshold of the target material rather than the laser intensity.
