It is well known that the laser–target interaction at high power and high laser intensity may result in the emission of strong electromagnetic pulses with frequencies in the range from tens of MHz to a few GHz and the duration of hundreds of nanoseconds. It was recently pointed out that the electric polarization of the target and the resulting neutralization current play an important role in the electromagnetic pulses emission. The target charge and the neutralization current generated with laser pulses of 30 fs to several ps duration were studied in detail at the Eclipse laser facility at CELIA, Bordeaux, with the laser pulse energy at the level of up to 100 mJ on target. In this contribution we report on the measurements of the target charge and the electromagnetic pulses performed at the 10 TW fs laser
