It is found that under the synchroresonance condition, the first-order perturbative electromagnetic energy fluxes will contain a "left circular wave" and a "right circular wave" around the symmetrical axis of the Gaussian beam, but the perturbative effects produced by the + and × polarization of the GW have a different physical behaviour. For the high-frequency relic GW with vg=10^(10) Hz, h=10^(-30), recently expected by the quintessential inflationary models, the corresponding perturbative photon flux passing through the region 10^(-2)m^(2) would be expected to be 104 s^(-1). This is the largest perturbative photon flux we have recently analysed and estimated using the typical laboratory parameters.展开更多
