  Abstract:
After analyzing the interaction of an intense linearly polarized microwave, field weaker than atomic field, with a dilute gas, the production of a plasma is studied. It is shown that the electron distribution function obtained is nonequilibrium and anisotropic. By considering the interaction of the high-frequency electric field with the produced plasma the dispersion relation of oscillations in the produced plasma is obtained. The parametric instability is studied for the produced plasma when instability frequency is higher than ion plasma frequency. Calculations show that the harmonic generation takes place in the produced plasma.
