Abstract
A simple extension of Miller and Nordland's interference method for determining relative signs of nonlinear optical coefficients is given. The extended method uses a (1/4)λ retardation plate to interchange ``simple'' and ``complex'' interference signals. This makes it possible to determine relative signs of coherence lengths as well as nonlinear coefficients without independent measurements of indices of refraction.This publication has 4 references indexed in Scilit:
