High harmonic generation and QED effects induced by relativistic oscillating mirror (Conference Presentation)

Paper Abstract

The laser-plasma interactions are dominated by the QED regime since intensities of the forthcoming laser facilities are approaching 10^{23-24} W/cm^2. Here we present the high brightness γ-photon emission and e^+e^- pair creation accompanied with the high harmonic generation. Relativistic oscillating mirror reflects the incident intense laser field and generates the focused attosecond pulse with enhanced intensity. A large number of high energy photons are emitted by the collisions between the radiation trapped electrons and the high harmonic pulses. The corresponding photons are counter-propagating through the strong laser field which provide a large cross section for pair creation. Relativistic positron bunches are generated and further accelerated in the reflected laser field.
