Resonant Condition for Wake Field Excitation in Rare Plasma
The wake-field excitation by intense laser pulse in rare plasma is investigated. The wake-field excitation depends on laser pulse width. The resonant condition is given, as the laser intensity increases, the optimum laser pulse width decreases from the half of the plasma wavelength in a very low laser intensity. In rare plasma, the strength of the wake-field depends on the background plasma density, while the maximum wake potential of wake-field is dependent on it.
