<title>Recent developments and results in 2D acousto-optic light deflection</title>

Abstract

A novel approach for one and two dimensional acoustooptic deflector design is presented. Two dimensional deflectors are optimally built of two adjacent Bragg cells in acoustically rotated configuration. The depleting effect of second order diffraction is compensated by a small change of the optical incidence angle. High bandwidth devices working below 100 MHz acoustic frequency and 1 W acoustic power are reported. . Several experimental results on deflectors for 633 nm and 1064 nm optical wavelengths are presented.

Laboratory tools and e-learning elements in training of acousto-optics

“…Then a boom in applied acousto-optics initiated from the various light controlling AO devices, such as traveling and standing wave modulators 4 and switches 5 , single or multi-dimensional deflectors 6 , tunable filters 7 and frequency shifters 8 to the sophisticated AO signal processing systems such as a real time power spectrum analyzer 9 , direction of arrival processor 10 , or 3-dimensional (3D) AO light steering in multi-photon microscopy 11 . This progress seemed to cease by the spreading of laser diodes allowing a direct fast modulation of light.…”
