Abstract
A high-accuracy method for determining the chemical composition of non-stoichiometric lithium niobate crystals is proposed based on precise measurements of birefringence of thin substrates using the laser ellipsometry in transmission. It is shown that, for compensators made of LiNbO3, this method allows one to monitor the ratio Li/(Li + Nb) with an accuracy of up to ∼10−8 at λ = 0.6328 μm. The accuracy is limited by temperature fluctuations of the crystal.
