Abstract. I will discuss signals generated by gravitational waves (GWs) in resonant cavity experiments. Experiments designed for the detection of axion dark matter only need to reanalyze existing data to search for GWs in the GHz range with strains as small as h ∼ 10^{−22} − 10^{−21}. This is still far from the Nucleosynthesis (BBN) bound on primordial sources, but it is the best direct constraint that we can currently obtain in the laboratory. I will further discuss how a heterodyne detection setup can open up a much larger detection window (roughly in the kHz to GHz range) and possibly be sensitive to more realistic sources of GWs. To get to these results I will correct some long standing misconceptions present in the literature on the calculation of the GW signal.
