On the synergic approach toward the experimental realization of interesting fundamental science within the framework of relativistic flying mirror concept

The relativistic flying parabolic mirror can provide a higher laser intensity than the intensity a current laser system can reach via the optical-focusing scheme. A weakly relativistic laser intensity (1.8 × 10 ^17 W/cm ^2 , η = 0.29 ) can be intensified up to a super-strong intensity of >1× 10 ^27 W/cm ^2 ( η≈ 2.2 × 10^4 ) by the relativistic flying mirror. Such a super-strong field can be applied to study the strong-field quantum electrodynamics in perturbative and non-perturbative regimes. In this review, the analytic derivations on the field strength and distribution obtained by the ideal relativistic flying parabolic mirror have been shown under the 4 π -spherical-focusing approach. The quantum non-linearity parameter is calculated when such a super-strong field collides with the high-energy γ -photons. The peak quantum non-linearity parameter reaches above 1600 when the 1-GeV γ -photon collides with a super-strong laser field reflected and focused by the relativistic flying mirror driven by a 10 PW laser pulse.
