Abstract
In this work, we demonstrate the coupling and emission of radio-frequency (RF) signals from laser-guided discharge in ambient air. The produced 100-cm long plasma-antenna is broadband and can emit RF signals for more than 2 ms, which corresponds to an enhancement of the plasma-antenna lifetime of 4 orders of magnitude relative to previous demonstrations using laser-based plasma filamentation. The generation of large diameter plasma-antennas in the air allows to broadcast RF signals efficiently from ~10MHz to few tens of GHz.
