Paper Abstract

We review the role of acousto-optic (AO) Bragg modulators in spatial filtering. For lowpass spatial filtering, we use the Bragg-scattered beam, whereas for highpass filtering, we employ the forward scattered beam. Using the forward-scattered beam results in cross-derivative operation applications when two orthogonally oriented AO Bragg modulators are used. Using the Bragg-scattered beam, we propose suppression of beam fanning countered in nonlinear optics. In most cases our theory is verified by experimental results and computer simulations.
