When high-intensity laser interaction with matter enters the regime of dominated radiation reaction, the radiation losses open the way for producing short pulse high power ray flashes. The -ray pulse duration and divergence are determined by the laser pulse amplitude and by the plasma target density scale length. On the basis of theoretical analysis and particle-in-cell simulations with the radiation friction force incorporated, optimal conditions for generating a -ray flash with a tailored overcritical density target are found.

Radiation reaction (RR) effect, which is a back reaction acting on a charged particle which emits radiation due to its acceleration, is important for such as electrons in synchrotron accelerators or high energy charged particles in the universe. For electrons irradiated by intense laser pulse, RR effect has been neglected so far, but as the laser intensity increases beyond roughly W/cm, it is expected to play an important role. In this study we investigated -ray generation via RR effect. When irradiating 10 PW, 30 fs laser pulse onto thin layer of carbon target, -ray which is as short as the laser pulse, and the total energy is 96 J which is 32% of the incident laser pulse is generated. The -ray power of 2.8 PW which is much higher than those generated by any other devices. We discuss the possibility of laser-driven -ray source.

In the interactions of peta-watt class laser pulses and matters, a radiation reaction effect on an electron motion driven by the strong laser field plays an important role. The effect of radiation reaction is expected to lead to the generation of high flux of photons in the energy range of -rays. In order to evaluate the detail of the -ray characteristics and efficiency, we developed a Particle-in-Cell code incorporating the radiation reaction effect by using Landau-Lifshitz equation. From the numerical analyses, it is found that the generated -ray pulse has quite unique features such as high power, short duration, high directionality, and high conversion efficiency when choosing the optimum conditions. We showed how to control the photon number, photon energy, pulse duration and so on. These studies lead us to propose a new source of laser-driven -rays via radiation reaction effect.
