A wide-band transducer for an acousto-optic deflector is described. The transducer is a chirped-frquency interdigital transducer with electrodes tilted to satisfy the isotropic Bragg condition. A simple theoretical model of the device is presented and numerical calculations of the frequency response indicate a wide operational bandwidth. A brief description of a direct optical-projection lithographic system used to fabricate deflectors with minimum electrode widths of ~1 μm is also included.

It is known that one of the ways to increase the energy efficiency of acousto–optic devices is to use ultrasound beams with a higher power density. It has been established experimentally that the use of a partially electroded ultrasonic transducer significantlyincreases the energy efficiency of the acousto–optic modulator of terahertz radiation. In addition, the operation of an acousto–optic deflector of terahertz radiation with the use of a sectioned ultrasound transducer was theoretically investigated. It showed that a deflector of this kind enables one to achieve higher angular resolution.

Abstract The paper considers advantages and special features of an acousto-optic method for the development of a functional device for spatial and temporal control of laser light and reports results of investigations to create a two-directional acousto-optic laser scanner with diffraction efficiency as high as 80 percent or better. An acousto-optic deflector on a paratellurite crystal operating under the Bragg diffraction condition with a lithium niobate piezoelectric acoustic transducer was developed and tested experimentally. The results of this work can serve as a basis for the development of prototype functional acousto-optic devices for spatial and temporal control of laser light and their application to create laser television images.

To form a multibeam radiation pattern, it is proposed to use the axial geometry of acousto-optic interaction in paratellurite. In the single frequency mode, the use of this geometry for angular scanning is characterized by a dip in the frequency response. Optimization of a multifrequency radio signal makes it possible to efficiently divide laser radiation into several beams with maintaining the fundamental advantages of axial geometry: minimum crystal size and power consumption. Keywords: acousto-optic diffraction, acousto-optic deflector, axial geometry, multifrequency mode, paratellurite.

In two configurations, a solid-state acousto-optic (AO) deflector or modulator is mounted in a 0.5 m monochromator for background correction with inductively coupled plasma atomic emission spectrometry (ICP-AES). A fused silica acousto-optic modulator (AOM) is used in the ultraviolet (UV) spectral region applications while a glass AO deflector (AOD) is used for the visible (VIS) region. The system provides rapid sequential observation of adjacent on- and off-line wavelengths for background correction. Seventeen elements are examined using pneumatic nebulization (PN) and electrothermal vaporization (ETV) sample introduction. Calibration plots were obtained with each sample introduction technique. Potable water and vitamin tablets were analyzed. Flame atomic absorption (FAA) was used to verify the accuracy of the AO background correction system.

Spot array generation is essential for optical computing architectures based on free-space interconnections. Acousto-optic (AO) deflectors are potentially attractive for reconfigurable array generation or interconnection because of their large space bandwidth product and switching times of a few microseconds. In this paper, we describe the procedure and present experimental results of using a large aperture integrated two-dimensional (2-D) AO deflector to generate reconfigurable 2-D spot arrays. The generation of 2-D spot arrays is achieved by driving each of two orthogonally mounted AO deflectors with a high-frequency carrier that is phase modulated with an electronic equivalent of a holographic phase grating. The carrier deflects the incident beam by the Bragg angle, while the modulating signal gives rise to the spot pattern. The 2-D AO spot array is realized as the outer-product of two 1-D spot arrays. 1-D phase grating structures were calculated using several nonlinear optimization techniques including a genetic algorithm and the Gerchberg-Saxton algorithm. In our experiments, the AO device was used for realizing both discrete (e.g., binary, 4-level) and continuous phase gratings. The continuous phase profiles give higher diffraction efficiency. Practical limitations encountered in the generation of 13x13,21x21 and 50x50 spot arrays are discussed.
