We describe a high speed 3D Acousto-Optic Lens Microscope (AOLM) for femtosecond 2-photon imaging. By optimizing the design of the 4 AO Deflectors (AODs) and by deriving new control algorithms, we have developed a compact spherical AOL with a low temporal dispersion that enables 2-photon imaging at 10-fold lower power than previously reported. We show that the AOLM can perform high speed 2D raster-scan imaging (>150 Hz) without scan rate dependent astigmatism. It can deflect and focus a laser beam in a 3D random access sequence at 30 kHz and has an extended focusing range (>137 μm; 40X 0.8NA objective). These features are likely to make the AOLM a useful tool for studying fast physiological processes distributed in 3D space

“…Several techniques havebeen used to achieve higher center frequency tangential phase matching in slow shear TeO, Bragg cells. These standard techniques include: 1) acoustically rotated off-axis operation [2] and 2) optically rotated off-axis operation [2,3].…”

The phased array transducer, when combined with the anisotropic Bragg interaction, provides a unique combination of features not available with the usual acoustical or optical rotation schemes used in the design of slow shear TeO, Bragg cells. A general theory for a phased array Bragg interaction in a birefringent medium is applied to the design of a60 MHz bandwidth, 5 0 p time-aperture slow shear TeO, Bragg cell. A 90 M H z center frequency device designed for 810 nm illumination with a 12-element Gaussian apodized phased array transducer with 154 pm element spacing oriented lo from [llO] was fabricated. The device exhibited the design center frequency and bandwidth with over 30%/ W peak diffraction efficiency with a fully illuminated aperture. The device exhibits Hecht limited two-tone third order intermodulation products over at least half of the time-aperture.
