Investigation on the Full-Aperture Diffraction Efficiency of AOTF Based on Tellurium Dioxide Crystals
The influence of acoustic field distribution and temperature variations on the full-aperture diffraction efficiency of non-collinear acousto-optic tunable filters (AOTFs) was investigated based on tellurium dioxide crystals.The strong acoustic anisotropy of the crystal induces non-uniform acoustic energy distribution, limiting the overall diffracti
