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

Abstract

AbstractThe 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 $$\times$$ × 10$$^{17}$$ 17 W/cm$$^2$$ 2 , $$\eta = 0.29$$ η = 0.29 ) can be intensified up to a super-strong intensity of $$>\textrm{1}\times$$ > 1 × 10$$^{27}$$ 27 W/cm$$^2$$ 2 ($$\eta \approx 2.2 \times 10^4$$ 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$$\pi$$ π -spherical-focusing approach. The quantum non-linearity parameter is calculated when such a super-strong field collides with the high-energy $$\gamma$$ γ -photons. The peak quantum non-linearity parameter reaches above 1600 when the 1-GeV $$\gamma$$ γ -photon collides with a super-strong laser field reflected and focused by the relativistic flying mirror driven by a 10 PW laser pulse.
