title: Refractive index detector using Zeeman interferometry.
abstract: We discuss the theory and error analysis for an ultrasensitive refractive index detector based on the two frequency Zeeman effect laser. Experimental measurements on gases agree fairly well with predictions. With a 5-cm pathlength, the typical interferometry stability is Deltan = 8 x 10(-9)/h. Resolution is Deltan = 1 x 10(-9).
