Radiation reaction is one of the remaining big problems in theoretical physics. When an electron has high energy, radiation from this electron might become significant. Since this regime involves laser intensities over W/cm, we need to consider it under next generation laser-electron interactions. Moreover, this radiation reaction is studied as an electron model in classical physics. Therefore, the research of ultrahigh intense laser-high energy electron interactions has the potential to take us to the center and essence of physics. However, the Lorentz-Abraham-Dirac theory which is the standard model of radiation reaction, has a difficulty of the run-away solution. In this paper, the history of the researches of radiation reaction, our recent studies and the experimental design of this process will be presented.
