We describe a 500 MHz, 2 microsecond time aperture, Liro03 acousto -optic Bragg cell with minimal acoustic beam spreading and high diffraction eficiency.The cell utilizes an apodized phased array transducer. This device is particularly useful in wide bandwidth acousto -optic processing applications, such as optical correlation, where diffracted optical beam quality is important.
