Intensities of the forthcoming laser facilities are approaching 1023-24 W/cm2. With such a high
intensity, the laser-plasma interactions are dominated by the QED regime. In this work, 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 intensity enhancement. A large number
of high energy photons are emitted by the radiation trapped electron colliding with the high
harmonic pulse. The corresponding photons are counter-propagating through the strong laser
field which provide a high probability for pair creation. Relativistic positron bunches are
obtained and further accelerated in the reflected laser field. This regime may be beneficial for
the potential experiments carried on the large laser facilities such as ELI-beamlines1.
