Abstract

In this work, we present the first experimental upper limits on the presence of stochastic gravitational waves in a frequency band with frequencies above 1 THz. We exclude gravitational waves in the frequency bands from (2.7−14)× 10 14 (2.7−14)×1014 Hz and (5−12)× 10 18 (5−12)×1018 Hz down to a characteristic amplitude of h min c ≈6× 10 −26 hcmin≈6×10−26 and h min c ≈5× 10 −28 hcmin≈5×10−28 at 95% confidence level, respectively. To obtain these results, we used data from existing facilities that have been constructed and operated with the aim of detecting weakly interacting slim particles, pointing out that these facilities are also sensitive to gravitational waves by graviton to photon conversion in the presence of a magnetic field. The principle applies to all experiments of this kind, with prospects of constraining (or detecting), for example, gravitational waves from light primordial black-hole evaporation in the early universe.
