Abstract

A method of measuring phase nonreciprocity in materials using a Sagnac interferometer is proposed and implemented in which the working point is shifted into the region of maximum slope of the interference pattern by means of an absorbing exit mirror. The principal advantage of this method over the laser technique is that there are no stringent constraints on the losses in the materials. This method was used for the first time at 0.83 μm to measure the nonreciprocal linear birefringence in a LiIO3 crystal in a transverse magnetic field.
