| Abstract: | Due to the long optical wavelengths of the mid-infrared region and to the low acoustic shear wave velocities of mercury halides, the high acoustic frequency solution of the acousto-optic wave-vector diagram can be used to design new high resolution acousto-optic filters, such as reflective AOTFs and AOPDFs, which are technically impossible to realize in the UV, visible and near-infrared regions. |
