Propagation of Laser-Driven Electromagnetic Pulses in Laser Target Areas

During high intense laser target interaction a strong electromagnetic pulse (EMP) is generated which can potentially disturb the well performing of the experiment. The electromagnetic interference (EMI) due to the EMP not only affects devices present in the vacuum chamber but also in the target area where it may compromise the performance or operation of electronics and device controllers.In this work we report the measurements of EMP inside the laser target area at Centro de Laseres Pulsados (CLPU) during high intense laser-target interaction experiments. The experimental results show how the amplitude and spectrum of the EMP in the target area is different from the one inside the target chamber (TC). At last Finite element method (FEM) simulation results are shown and compared with experimental results.
