Title: Kinetic study on non-thermal volumetric plasma decay in the early afterglow of air discharge generated by a short pulse microwave or laser

Abstract

This paper reports a kinetic study on non-thermal plasma decay in the early afterglow of air discharge generated by short pulse microwave or laser. A global self-consistent model is based on the particle balance of complex plasma chemistry, electron energy equation, and gas thermal balance equation. Electron-ion Coulomb collision is included in the steady state Boltzmann equation solver to accurately describe the electron mobility and other transport coefficients. The model is used to simulate the afterglow of microsecond to nanosecond pulse microwave discharge in N{sub 2}, O{sub 2}, and air, as well as femtosecond laser filament discharge in dry and humid air. The simulated results for electron density decay are in quantitative agreement with the available measured ones. The evolution of plasma decay under an external electric field is also investigated, and the effect of gas heating is considered. The underlying mechanism of plasma density decay is unveiled through the above kinetic modeling.

  • A model is developed for calculating pump parameters of the active medium of a supersonic electric-discharge CO laser excited by a microwave discharge. A variant of the design of such a radiation source is described. Calculations are performed both for the 'hot' variant of the radiation source, when the gas mixture is produced by burning the fuel in a gas generator, and the 'cold' variant, when the gas mixture is supplied to the discharge region from gas vessels. The regions of optimal values of the reduced field strength and parameters of the gas mixture for the 'cold' variant are determined.more » It is shown that the parameters of the active medium obtained in the 'hot' variant correspond to the parameters of highly efficient radiation sources reported in the literature.

  • The quasistatic magnetic field generated by short laser pulse in a uniform rarefied plasma is found analytically and compared to that of two-dimensional particle simulations. It is shown that an axisymmetric laser pulse generates an azimuthal magnetic field the structure of which is rather complicated inside the laser pulse body. Behind the pulse in the wake region the magnetic field contains a component that is homogeneous in the longitudinal direction and a component that is oscillating at the wave number 2k{sub p}, where k{sub p} is the wave number of the plasma wake. Particle simulations confirm the analytical results andmore » are also used to treat the case of high intense laser pulses. {copyright} {ital 1997 American Institute of Physics.}« less
  • We have measured high resolution copper K{alpha} spectra from a picosecond high intensity laser produced plasma. By fitting the shape of the experimental spectra with a self-consistent-field model which includes all the relevant line shifts from multiply ionized atoms, we are able to infer time and spatially averaged electron temperatures (T{sub e}) and ionization state (Z) in the foil. Our results show increasing values for T{sub e} and Z when the overall mass of the target is reduced. In particular, we measure temperatures in excess of 200 eV with Z {approx} 13-14. For these conditions the ion-ion coupling constant ismore » {Lambda}{sub ii} {approx} 8-9, thus suggesting the achievement of a strongly coupled plasma regime.« less
  • We have demonstrated the short pulse, high power microwave radiation source using an ultraviolet laser-induced sheet plasma mirror in a gas-filled x-band rectangular waveguide from the conventional microwave sources and components. A laser-induced sheet plasma with an overdense plasma acts as a plasma mirror. The long pulse propagating in the gas-filled waveguide was sliced by the sheet plasma mirror at two different points along the waveguide. We observed about twice the power of the pulse by adding the two sliced microwave pulses produced by this scheme. A maximum peak power of 200 kW with a pulse duration of 10 nsmore » (full width at half maximum) from the long microwave pulse source with a pulse duration of 0.8 mus was observed.« less
  • It is demonstrated experimentally that the lifetime of the afterglow plasma of a high-current pulsed discharge in a dielectric tube filled with a mixture of argon with saturated mercury vapor is longer than 1 ms. Such a long lifetime, during which the electron density decreases from 10{sup 14} to 10{sup 12} cm{sup -3}, is explained by the chemi-ionization of mercury vapor by long-lived metastable argon atoms. During this time, the afterglow plasma can serve as a microwave waveguide for a weakly damped low-noise E{sub 0}-type axisymmetric surface mode, which allows one to use it for transmission of signals in themore » centimeter wavelength range.« less
