Paper Abstract

A new design for a wide angular aperture Lithium Niobate acousto-optic Bragg cell is proposed. Parallel tangents, beam steering, and an acousto-optic interaction in a rotated 60 degree(s)-YZ plane are used simultaneously, which enhances the product of acceptance angle, bandwidth, and diffraction efficiency to be larger than that of isotropic acousto-optic Bragg cells by more than one order of magnitude. The analysis and optimum design procedure for acoustic beam steering in birefringent acousto-optic diffraction with the parallel tangents condition fulfilled is established and is essential for obtaining the maximum value of the above mentioned product. The acousto-optic interaction in the rotated YZ plane is analyzed and is important to obtain high diffraction efficiency for most cases where the parallel tangents condition is used. The optimal design of a wide angular aperture Lithium Niobate device working at 514.5 nm and with a center frequency of 150 MHz is carried out and is being fabricated.
