Dipole radio-frequency power from laser plasmas with no dipole moment
The radio-frequency power radiated from laser-target plasmas in a vacuum can
be orders of magnitude greater than expected from such sources that have a
negligible electric dipole moment. A model combining the Tidman-Stamper circuit
model of a laser-target plasma with the theory of radiation from currents
immersed in plasmas, however, predicts scaling of electric-dipole power
radiated from laser plasmas in agreement with experiments.Comment: 3 pages, 2 figures, as published in Applied Physics Letter
