A two year research and development program on electrooptically active perovskite crystals was initiated. The program consists of three parts growth improvement of potassium tantalate niobate KTN crystals, development of new complex perovskite compounds and electrooptical evaluation of these crystals. An improvement in the reproducibility and quality of KTN crystals was realized. A literature search for complex perovskite compounds and a computer program to generate the formulas and unit cell sizes for all possible complex perovskites are underway. Special methods for measuring the required electric, and electrooptic properties of crystals was developed and can now be used for studying the behavior of KTN crystals.
