The AOBD Acousto-Optic Beam Deflectors offer non-mechanical, high-speed laser beam scanning up to 200 MHz, delivering precise position control with angular resolution in the nanoradian (nRad) range. The solid-state design ensures unmatched reliability and consistency, making these devices ideal for demanding applications requiring agile and accurate beam positioning. The AOBD operates by applying an RF signal to a phased array piezoelectric transducer, generating an acoustic wave inside the crystal. This wave forms a dynamic diffraction grating, which deflects an incoming laser beam at a specific angle when the Bragg condition is satisfied. By adjusting the RF driving frequency, the grating spacing changes, resulting in precise control of the diffraction angle.
