This work consists on the characterization of a rectangular-aperture acousto-optic deflector. The characterization is carried out using two different laser beams: Gaussian and elliptical.
Furthermore, different wavelengths were used (488 nm, 561 nm, 637 nm). Several parameters of the AOD were measured: relative efficiency as a function of angular deflection, optimal angles of incidence, maximum bandwidth and optimal power and alignment to achieve maximum efficiency, all for different wavelengths.
