This Letter proposes a realistic implementation of the curved relativistic mirror concept to reach unprecedented light intensities in experiments. The scheme is based on relativistic plasma mirrors that are optically curved by laser radiation pressure. Its validity is supported by cutting-edge three-dimensional particle-in-cell simulations and a theoretical model, which show that intensities above 10^{25} W cm^{-2} could be reached with a 3 PetaWatt (PW) laser. Its very high robustness to laser and plasma imperfections is shown to surpass all previous schemes and should enable its implementation on existing PW laser facilities.
这封信件提出了一种现实可行的弯曲相对论反射镜概念，以在实验中达到前所未有的光强。该方案基于相对论性等离子体反射镜，其通过激光辐射压力光学弯曲。其有效性得到了最先进的三维粒子模拟和理论模型的支持，这些模型表明，使用 3 拍瓦（PW）激光可以达到超过 10^{25} W cm^{-2}的强度。该方案对激光和等离子体不完美情况具有非常高的稳健性，超过了所有以前的方案，应该能够在现有的 PW 激光设施上实现。
