Abstract
The collision of two real photons can result in the emission of axions. We investigate the performance of a modified light-shining-through-wall (LSW) axion search aiming to overcome the large signal suppression for axion masses ${m}_{a}\ensuremath{\ge}1\text{ }\text{ }\mathrm{eV}$. We propose to utilize a third beam to stimulate the reconversion of axions into a measurable signal. We thereby find that with currently available high-power laser facilities we expect bounds at axion masses between 0.5--6 eV reaching ${g}_{a\ensuremath{\gamma}\ensuremath{\gamma}}\ensuremath{\ge}{10}^{\ensuremath{-}7}\text{ }\text{ }{\mathrm{GeV}}^{\ensuremath{-}1}$. Combining the use of optical lasers with currently operating x-ray free electron lasers, we extend the mass range to 10--100 eV.
