I will discuss electromagnetic signals generated by gravitational waves (GWs) and light axion dark matter in microwave cavity experiments. In our proposed setup we generate and detect a heterodyne signal. This idea has the potential to cover a factor of 100 in mass on the QCD line and an extra 15 orders of magnitude of unexplored ALPs parameter space. Three prototypes for axion detection are in different stages of their development at SLAC, Fermilab and CERN. The SLAC prototype made a first data-taking run last year that I will briefly discuss. The same logic can be applied to gravitational waves, giving potentially one of the best detectors at high frequencies (between MHz and GHz).
