We consider a continuous optical discharge (COD) sustained by a weakly focused CO(2) laser beam and stabilized by a cold gas flow incident in the direction of the laser radiation propagation. We develop and examine a two-dimensional radiative gas-dynamic model for COD which uses realistic quasi-optics and takes refraction of the laser radiation in the plasma properly into account in describing the laser beam propagation. The model is applied to calculate the parameters of COD in the air flow as functions of the laser power and inlet velocity of the incident flow.

Radiative gas-dynamic model of a continuous optical discharge in a gravitational field: quasi-optical approximation Rafatov, İsmail (IOP Publishing, 2009-08-07) We consider a continuous optical discharge (COD) sustained by a vertically directed weakly focused CO(2) laser beam, in a gravitational field. We used a full two-dimensional radiative gas-dynamic numerical model for the COD, which uses realistic quasi optics and takes refraction of the laser radiation in the plasma properly into account in the description of the laser beam propagation. The model is applied to calculate the parameters of the COD in a converging CO(2) laser beam in free air atmosphere as a fu...
Perturbation analysis of sheath evolution, with application to plasma source ion implantation Bektursunova, RM; Demokan, O (IOP Publishing, 2001-02-07) A perturbation model has been developed to describe the evolution of an expanding plasma sheath around a cathode after a high-voltage negative pulse is applied to the cathode, simulating the conditions in devices such as those used for plasma source ion implantation. The set of governing equations consists of two coupled collisionless fluid equations for ions, and Poisson's equation and Boltzmann's assumption for electrons. The time-dependent, self-consistent expressions for the potential, ion density and i...
Modelling of a spherical electric discharge at atmospheric pressure under higher modes of incident microwaves Rafatov, İsmail; LELEVKIN, VM (Wiley, 2005-01-01) We present a spherical microwave discharge model, which takes into account the higher modes of the incident electromagnetic waves. The discharge model is constructed on the basis of the channel approximation of the LTE plasma. Numerical experiments are carried out for the discharge in an argon at atmospheric pressure. Results are presented for the characteristics of the discharge plasma against the external parameters (the size of the discharge chamber and the applied electromagnetic field mode, power and f...
Spatial stabilization of Townsend and glow discharges with a semiconducting cathode Salamov, BG; Ellialtioglu, S; Akınoğlu, Bülent Gültekin; Lebedeva, NN; Patriskii, LG (IOP Publishing, 1996-03-14) The physical processes determining the functions of an ionization system and especially the discharge stabilization by the distributed resistance of a semiconducting cathode in such a system are studied. The current-voltage (I-U) characteristics of the system with a semiconducting GaAs cathode are obtained experimentally as functions of the gap pressure P (16-760 Torr) and inter-electrode distance d (10 mu m to 5 mm), which are varied for the first time over very wide ranges. The experiments showed that the...
Electrical, photo-electrical, optical and structural properties of CdSe thin films deposited by thermal and e-beam techniques Hus, S. M.; Parlak, Mehmet (IOP Publishing, 2008-02-07) In this study, electrical, photo-electrical, optical and structural analyses of CdSe thin films deposited by thermal and e-beam evaporation techniques were carried out by measuring temperature dependent conductivity, mobility, photoconductivity under different illumination intensity, photoresponse, transmission and x-ray diffraction. As a result of these measurements, it was observed that the films deposited by the thermal evaporation technique have room temperature conductivity values approximately three o...
