Following Einstein's thought: interaction to be geometrizing, light interactions with plasmas are studied under the framework of general relativity theory.The dissertation is divided into three parts.Light propagating in moving media in which three different light interactions with plasmas are included is studied by using the effective metric theory in the first part: firstly photon acceleration by the electronic plasma wave induced by strong laser pulses is examined; next studies in the multi- photons ionization process, how does the laser - plasma interaction affect the multi- photons ionization rate; finally studied in how does the magnetization plasma in the magnetosphere of pulsars cause the spectrum of the radio radiation shifting and the gravitational redshift of the pulsar radiation is corrected.In the second part the effective metric model for light interacting with moving dispersive media has been established for the first time and the analogous model of Einstein gravity theory is generalized from non-dispersive medium to dispersive medium cases. Including three contents: first has established the effective metric model of light traveling in the moving dispersive media, and the electromagnetic horizon , electromagnetic black hole and the Hawking radiation generated via light interaction with moving dispersive media have been studied; next we investigate how electrons in plasmas experience the electromagnetic field interaction with charged particles in plasmas as an effective metric field and the dynamic equation for the electrons in plasmas is examined; finally we have studied how the unified effective metric is derived to describe the kinetics for a charged particle under the both action of gravity and electromagnetic force and the corresponding equation for a charged particle is investigated.The third part has studied the effects of the curved space-times induced by the local instantaneous ultra-intense energy originated from high-power and ultra-short laser...
