We propose a novel way to search for the dark photon ($A'$), the axion-like pseudo-scalar ($a$), the dark scalar ($\phi$), and the light dark matter ($\chi$) in the Compton process, $\gamma + e^- \rightarrow A'/a/\phi + e^-$ with $A'/a/\phi$ decaying into leptons, photons, or $\chi$'s (when permitted) for the mass ranges of 1 $\leq m_{A'/a/\phi} \leq$ 100 MeV/$c^2$ and 0.5 $\leq m_{\chi} \leq $ 50 MeV/$c^2$, respectively. We will review how current photon beam experiments (FOREST, GlueX, LEPS, and LEPS2) can use this new production mechanism of dark particles. We will discuss the expected sensitivities of these experiments on the kinetic mixing ($\epsilon$), the axion-like pseudo-scalar coupling to electron ($g_{ae}$), and the dark scalar coupling to electron ($y_e$).
