Paper Abstract

In this paper a new optimum design method of anisotropic acousto-optic deflector (AOD) with ultrasonic beam steering is introduced for two kinds of crystals: Tellurium Oxide (TeO2) and Lithium Niobate (LN). First anisotropic acousto-optic (AO) interaction geometric relationships in the two crystals are calculated. Then optimum design method and results, including design parameters and design curves of the two anisotropic AOD, are given through calculating Bragg loss vs acoustic frequency. Final curves of relative bandwidth vs relative length for the two anisotropic AOD are given. Compared with non-steering AOD, when relative bandwidth is equal to octave bandwidth, the relative length of steering AOD will increase 34.7% for TeO2 anisotropic AOD and 73.4% for LN anisotropic AOD, when relative length is satisfied condition into Bragg region, the relative bandwidth of steering AOD will increase 9.1% for TeO2 anisotropic AOD and 17.7% for LN anisotropic AOD.
