چکیده

We demonstrate the generation of Bessel beams using an acousto-optic array based on a liquid filled cavity surrounded by a cylindrical multi-element ultrasound transducer array. Conversion of a Gaussian laser mode into a Bessel beam with tunable order and position is shown. Also higher-order Bessel beams up to the fourth order are successfully generated with experimental results very closely matching simulations.

Acousto-optic signal processors for transmission and reception of phased-array antenna signals.

Novel acousto-optic processors for control and signal processing in phased-array antennas are presented. These processors can operate in both the antenna transmit and receive modes. An experimental acousto-optic processor is demonstrated in the laboratory. This optical technique replaces all the phase-shifting devices required in electronically controlled phased-array antennas.

Shaping of ultrashort optical pulses by using an integrated acousto-optic tunable filter.

Reshaping of ultrashort optical pulses at 1.53 ,um by using an integrated acousto-optic tunable filter is reported. Control of the optical pulse shape is accomplished by adjusting the different radio-frequency electrical signals driving the acousto-optic filter. This is to our knowledge the first demonstration of ultrashort pulse shaping using an integrated-optic device and establishes a new ap...

Two-Element Phased-Array Acousto-Optic Deflector at High Diffraction Efficiency: Scanning Range Broadening

An acousto-optic deflector with a two-element phased-array piezoelectric transducer is investigated at high diffraction efficiency (close to 100%). Significant broadening of the frequency band (and, thus, the angular scanning range) relative to the well-known low efficiency regime is theoretically predicted and experimentally demonstrated. Experiments with an off-axis deflector based on paratel...

Design of a double-pass shear mode acousto-optic modulator.

The design of a compact double-pass shear mode acousto-optic modulator for high power operation in the UV is presented. Using a spherical mirror retroreflector in the second pass to correct for beam deflection, changes in beam position and angle during frequency tuning can be eliminated. The use of the shear mode acousto-optic interaction offers several key advantages, but the strain-induced bi...
