Abstract
Ammonium oxalate (AMO) has one of the highest figures of merit of known electro-optical materials and is potentially very useful. Single crystals of AMO 2 cm X 2 cm X 4 cm were grown from aqueous solutions by the temperature lowering technique. The crystals were oriented by optical birefringence techinques used for biaxial crystals. Preliminary experiments indicate that a halfwave voltage in excess of 6 KV is required for a sample oriented such that one of its optic axes, the applied field and the light beam are collinear.
