We describe the radiofrequency emission taking place when 300 ps laser pulses irradiate various solid targets with an intensity of 10(16) W/cm(2). The emission of intense electromagnetic pulses was observed outside the laser target chamber by two loop antennas up to 1 GHz. Electromagnetic pulses can be 800 MHz transients, which decay from a peak electromagnetic field of E-0 congruent to 7 kV/m and H-0 congruent to 15 A/m. The occurrence of these electromagnetic pulses is associated with generation of hard x-rays with photon energies extending beyond 1 MeV. This contribution reports the first observation of this effect at the PALS facility.
