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 diffraction efficiency. To analyze this effect. https://www.machitoorchestranyc.com/product-category/moisturizer-2/
