Laboratory Gravitational Waves: Sources and Detection
摘要
Laboratory sources of gravitational waves are considered based on the interaction of intense laser radiation and matter and by means of electromagnetic radiation itself. It is shown that the perturbations of matter induced by powerful electromagnetic radiation with optical frequencies correspond to the high-frequency gravitational waves with the amplitude of the order \( {h}_0\sim 10^{-40} \) . Also, a system of standing electromagnetic waves in electromagnetic resonators is considered as a source of gravitational waves. It is shown that in this case the amplitude of gravitational waves depends on the difference in the frequency of standing electromagnetic waves as \( {h}_0\sim {\overset{\sim }{\omega}}^{-2} \) . This effect implies a significant increase in the amplitude of low-frequency gravitational waves induced by electromagnetic waves. Also, the obtained characteristics of the gravitational waves are used to assess the possibility of their registration by existing and prospective detectors.
