Abstract

We studied the growth and design of solid-solution crystal of mercurous chloride (Hg₂Cl₂) and mercurous bromide (Hg₂Br₂). The lattice parameters of the mixtures obey Vagard’s law in the studied composition range. The study demonstrates that properties are very anisotropic with crystal orientation, and performance achievement requires extremely careful fabrication to utilize theoretical AO figure of merit. In addition, some parameters such as crystal growth fabrication, processing time, resolution, field of view and efficiency will be described for imagers based on novel solid solution materials. It was predicted that very similar to the mercurous chloride and mercurous bromide solid solutions also have very large anisotropy, and acousto-optic figure of merit decreases significantly as function of the crystal orientation.
