Intrinsic birefringence
Webbirefringence of the optics used in the ALPS experiment must be known. An apparatus called a heterodyne polarimeter can be used to measure the birefringence of such … WebA novel and low-cost fiber birefringence measurement scheme is proposed and studied by a polarimetric fiber ring laser interrogated by beat frequency technique. In the fiber ring laser, modes splitting occur between two orthogonal polarization modes because of intrinsic fiber birefringence. As a result, two types of beat frequency signals ...
