Abstract: The birefringence of LiNbO3 crystals is measured using the method of laser "cone light" interference.. The precision is up to +0.001. Solid composition of LiNbO3 crystal is then obtained directly by using the "birefringence-solid composition" curve of LiNbO3 given by Oarruthers et al. It is found that this method is simple and convenient and is easy to practise. The precision is about an order of magnitude higher than that of chemical method.
