The detection of gravitational waves (GW) from astrophysical sources has opened a new era in physics. However, advances in high-energy laser systems make it possible to consider gravitational waves produced in the laboratory. In this work, the angular distribution and energy flux of gravitational waves radiated by high-power Laguerre–Gaussian beams are analysed. With a power of 
and frequency of 
Hz for the LG beams, the radiated GW frequency is twice the laser frequency and the maximal GW amplitude can reach 
which is quite small compared with the current detection threshold of around 
by LIGO. It is shown in Ejlli et al. (Eur Phys J C 79:1032, 2019) that the inverse Gertsenshtein effect is able to detect ultra high frequency gravitational wave with frequency up to Hz and strain around 
which may provide a viable way to measure gravitational waves produced by high-power lasers in the future.
