For demonstrating feasibility of ERL-based Compton sources, we conducted an experiment at the Compact ERL (cERL), where 7-keV X-ray photons with narrow bandwidth, 0.4% (rms) with an opening angle of 0.14 mrad, were generated by colliding an electron beam of 20 MeV with a laser of 1064 nm wavelength. In this talk, we overview the status of ERL-based Compton sources including relevant accelerator and laser components and discuss future perspectives of ERL-based Compton sources for keV and MeV photons.
