Abstract
An acousto-optic deflector with a layered structure (10) comprises at least two acousto-optic crystals (12), to each of which at least one electro-acoustic transducer (14) is connected, and the adjacent crystals (12) are separated by an acoustic isolator (16). A method for deflecting an optical beam using the acousto-optic deflector (10), comprises creating a first acoustic wave (15′) in a first acousto-optic crystal (12′) using a first electro-acoustic transducer (14′) connected to the first acousto-optic crystal (12′), and creating a second acoustic wave (15″) in a second acousto-optic crystal (12″) using a second electro-acoustic transducer (14″) connected to the second acousto-optic crystal (12″) and arranged between the first acousto-optic crystal (12′) and the second acousto-optic crystal (12″).
