Two-dimensional transfer functions of AOTFs in HIO3 crystal

A series of simulated acousto-optic tunable filter two-dimensional transfer functions for a biaxial HIO3 crystal is presented. The simulations were performed under noncritical phase matching condition in XZ and YZ planes of the crystal. Each figure includes the simulated transfer function and a Bragg angle-frequency diagram indication the operation point. The simulations are made for the optical wavelength of 1064 nm. The list of the files and corresponding simulation parameters is provided in “List of Figures.xlsx”. The results for XZ plane (13 files) include 8 cases of anisotropic (slow-to-fast or fast-to-slow) diffraction, 2 cases of axial diffraction, and 3 cases of isotropic (slow-to-slow) diffraction. The results for YZ plane (9 files) belong to anisotropic (slow-to-fast) diffraction type. All transfer functions are classified into four topological types: “X”, “O”, “V”, and “U”.
