“…I_n the optical Faraday effect [3,4,5], polarised light is passed through a crystal which, when exposed to a magnetic field, causes a rotation of the polarisation. This polarisation rotation is proportional to the component of the magnetic field along the direction of light propagation, the crystal length and the Verdet constant.…”

Very fast current transients (10 A, 5 GHz) have been measured using the Faraday rotation in CdMnTe sample. RF magnetic fields with an amplitude of < 10 G have been measured, despite the laser intensity noise (at these bandwidths) and the noisy environments. This paper describes a technique whereby the insertion loss is minimised and the effect of the laser intensity noise reduced, enabling these small RF fields to be measured for the first time.
