Here, we propose an experimental diagnostic to measure the temporal (sub-ps) and spatial distribution of kilo-Tesla magnetic fields generated at the rear side of NCD targets under single-pulse, ultrashort (45 fs) laser-plasma interactions. This technique is based on the Faraday rotation induced on an initially linearly polarized probe beam propagating through a strong parallel magnetic field in a plasma and on the imaging of the associated projected polarization states. 2D simulations were performed using relativistic particle-in-cell code to numerically explore the magnetic field generated under MVA regime in boron-like-fusion targets and the resulting Faraday rotation. The simulation and analytical results demonstrate that this diagnostic may be experimentally implemented in existing laser facilities.
