Description
We propose a novel Light-Shining-Through-a-Wall (LSW) scheme that utilizes the ultra-strong electromagnetic fields of laser-driven plasma wakefields for highly efficient, in situ axion generation. Moreover, by injecting a coherent seed field into the regeneration region, the axion-induced photon signal is coherently amplified via constructive interference, offering a pathway to probe axion-photon couplings at the $g_{a\gamma\gamma}\sim10^{-12}\text{GeV}^{-1}$ level without requiring resonant cavities.
