Different types of instabilities are observed in the thermodynamically nonequilibrium Earth's ionosphere. Effective energy exchange process among waves may takes place through nonlinear interaction modes because of availability of free energy. We consider gradients in density and magnetic field is present in the system which support drift wave turbulence. In this study we concern on the wave energy up conversion of electrostatic nonresonant lower hybrid wave through plasma maser instability in the mid-altitude ionospheric region. We have formulated the growth rate of lower hybrid wave by Vlasov-Poisson mathematical frame and estimated its value by observational data.

Unique forms of nonlinear wave energy exchange phenomena are observed in the Earth’sionosphere region. Energy upconversion of nonresonant plasma waves in the top ionospheric and auroral zone are noticed.Origin of these phenomena are tried to explained by linear andnonlinear theoretical approach.Wave-wave and wave-particle-wave interaction processes may be possible role takes place here.In this theoretical investigation we wish to derive probable growthrate expression of high frequency electromagnetic O-mode wave in the presence of low frequency electrostatic ion sound wave through wave-particle interaction process known as plasma maserinstability and estimate its value by using observational data.

From ground and satellite based observatories, various forms of nonlinear effects and plasma waves instabilities are observed in the Earth’s ionosphere. In this paper we present a brief review on nonlinear wave-particle interaction energy exchange mode plasma maser instability and on probable growth rate of high frequency non-resonant waves at different regions of the Earth’s ionosphere.

Wave energy up conversion of high frequency plasma wave in presence of low frequency plasma wave are studied in both space and laboratory plasma. In the ionosphere different forms of free energy sources are coexisting and energy exchange process takes place among plasma waves and particles. Through plasma maser effect ionospheric plasma particles may be transferred energy nonlinearly to high frequency mode through a modulated electric field in the presence of electron density gradients. In this paper we have explained how energy from drift wave is transferred to non-resonant ion sound wave. Including plasma inhomogeneity effect in our model the growth rate of ion sound wave in the Earth's ionosphere in presence of drift wave turbulence estimated using observational data.

In the Earth's ionosphere wide range of instabilities are observed due to presence of free energy sources. Wave-wave and wave-particle interaction processes may take place here. Through wave-particle interaction process wave energy can be pumped up from the system for amplification of high frequency non-resonant wave where low frequency turbulence is present. In this study we have considered ionosphere as homogeneous medium and wish to investigate probable amplification of nonresonant Langmuir wave in the presence of resonant Lower hybrid wave through nonlinear wave-particle interaction. We have estimate growth rate of Langmuir wave using satellite observational data.
