About
We propose a new method for detecting high-frequency gravitational waves (GWs) using high-energy pulsed lasers. Through the inverse Gertsenshtein effect, the interaction between a GW and the laser beam results in the creation of an electromagnetic signal. The latter can be detected using single-photon counting techniques. We present the minimal strain of a detectable GW which only depends on the laser parameters. Interestingly, we find that a resonance occurs in this process when the frequency of the GW is twice the frequency of the laser. With this method, the ultra-high GW-frequency range 10^{13} - 10^{19} Hz is explored non-continuously for strains $h \gtrsim 10^{-20}$ for current laser systems and can be extended to $h \gtrsim 10^{-26}$ with future generation facilities..
