Abstract
Modulation of the polarization state of a probe beam is used for the c ontactless detection of the alternating voltage induced across a Bi12T iO20 sample by a spatially oscillating interference pattern. The measu red voltage is up to 78% of the theoretical limit. The advantages of t his technique as compared with conventional short-circuit current meas urements are discussed, and a new all-optical technique for Hall mobil ity measurements is proposed.
