Paper Abstract

Large crystals of Hg2Cl2 and Hg2Br2 (48 mm in diameter, up to 600g in weight) have been grown by self-seeded contactless Physical Vapor Transport (PVT) technique in closed ampoules in vertical configuration. Seed selection was accomplished in the small diameter tubing at the ampoule tip. Material purification was done by resublimation processing. The crystals show high transparency, with good transmittance and good crystallographic quality. An acousto-optic modulator built from the Hg2Cl2 crystal showed good performance consistent with predicted device parameters.
