Abstract

Acousto-optic Bragg diffraction is an electronically controllable angular-selective type of laser beam scattering. A variety of transfer functions of acousto-optic Bragg diffraction in crystals is observed from the point of view of laser beam shaping. Those include one-dimensional isotropic filtering, and two-dimensional anisotropic X- and O-type transfer functions. Those types of transfer functions are useful for obtaining flat-top laser beam shaping, focusing, and wavefront sensing. Dynamic generation of ultrasonic waveforms is discussed as a method for adaptive control of the transfer function shape.
