摘要：

We present a model that elucidates the physics underlying the generation of an electromagnetic pulse from a feintosecond laser induced plasma channel. The radiation pressure force front the laser pulse spatially separates the ionized electrons from the heavier ions and the induced dipole moment subsequently oscillates at the plasma frequency and radiates an electromagnetic pulse.
