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
$m_a\geq 1 \text{eV}$. We propose to utilise 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 $0.5-6\text{eV}$ reaching $g_{a\gamma\gamma}\geq
10^{-7}\text{GeV}^{-1}$. Combining the use of optical lasers with currently
operating x-ray free electron lasers, we extend the mass range to
$10-100\text{eV}$.
