Pick-up coil detection of the inverse Faraday effect in Tb-doped aluminium-boron-silicate glass

Magnetic and electric properties of a quantum vacuum

“…Authors of ref. [126] suggest that these values could be reached with new laser facilities but the very small value of the induced magnetization remains an experimental challenge (Optical field induced magnetization as small as 10 −10 T are reported in [127]).…”

“…where we have used the relation µ 0 M (A m −1 ) = M (T). The authors of [126] suggest that these values could be reached with new laser facilities, but the very small value of the induced magnetization remains an experimental challenge (opticalfield-induced magnetization as small as 10 −10 T is reported in [127]). Symmetry considerations already applied to direct effects indicate that an inverse Kerr effect and inverse magnetoelectric birefringence effects exist in a vacuum as well.…”

Inverse Cotton-Mouton effect of the vacuum and of atomic systems

“…This effect is related to the Faraday effect as the ICME is related to the Cotton-Mouton effect. In the case of IFE measurements sensitivity in magnetization of the order of 10 −10 T has been reached [19]. The same kind of sensitivity should be reached in the case of ICME.…”

“…The values in Eqs. (17) and (18) are still below the sensitivity reported in [19], but new laser sources like the Extreme Light Infrastructure (ELI) [2] and the High Power laser Energy Research system (HiPER) [3] are supposed to reach intensities exceeding 10 29 W/m 2 increasing the expected ICME of vacuum at levels that should be detectable. In particular, taking also advantage of progress in tranverse pulsed magnetic field [18] and using a field of at least 30 T, a laser intensity of 5 × 10 25 W/m 2 , well below the possibilities of new facilities, will be sufficient to open up direct studies of quantum vacuum with powerful laser systems.…”
