A new method to determine the deuterium content of DKDP crystal with thermo-gravimetric apparatus

Measurement and control of the percentage of deuterium in single crystal DKDP samples is of considerable importance for the production of optical modulators and deflectors, optical frequency converters and other optical devices. A new method determine the deuterium content of DKDP crystal with thermo-gravimetric apparatus is developed in the article which implies the weighing of the initial material and products of thermal decay. This handy method of analysis requires merely 30–50 mg DKDP crystal sample to determine its deuterium content with high accuracy.
