Abstract:
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.

Abstract:
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:
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.

Abstract:
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.

Abstract:
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.

Abstract:
The work is devoted to the development of an acousto-optic deflector for a laser-beam guidance system (LLSN) of missiles. LLSN is used in semiautomatic portable missile systems to destroy hostile targets of various types. An analysis of the methods for constructing such systems has shown that the most promising devices with pulse-code modulation using semiconductor pulsed lasers. The article provides a diagram and describes the principle of operation of the LLSN with pulse-code modulation. A problematic issue in the implementation of such a system is the development of a device for deflecting a laser beam, through which the missile is guided to a target. Scanning mechanical devices that are currently in use have a complex design, significant dimensions and weight, and limited performance. The article proposes to use an acousto-optic deflector to deflect the laser beam within the information field of the guidance system, which is devoid of these disadvantages, since it replaces the mechanical scanning device with an electronic one. The purpose of the article is to determine the main parameters of the acousto-optical deflector. The article discusses the principle of operation of an acousto-optic deflector. It is noted that glasses based on germanium chalcogenides, in particular, glass with the composition Ge2.17As39.13S58.70, have especially low values of acoustic losses (α <1 dB / cm). The largest deflection angle of the laser beam will be observed with Bragg diffraction. Relationships are given that can be used to determine the main characteristics of the deflector: the angle of deflection of the laser beam, the modulation frequency of the acoustic wave, resolution, speed, and others. When using the above ratios for the typical parameters of the existing guidance system, the values of the indicated characteristics are calculated.

Abstract:
The acousto-optic control of the energy profile of laser radiation is considered. A highly efficient multibeam Bragg diffraction mode with a combination of beams close in angular space, forming an averaged pattern in the form of a single beam, is used. In this case, the two-dimensional intensity profile is realized as a product of two independent one-dimensional profiles. On the basis of a polarization-independent two-coordinate acousto-optic deflector, several profiles (including a close to uniform one) were experimentally obtained with a total efficiency of no less than 85% and a profile change time of about ten microseconds. This method can be used in systems for processing materials with powerful lasers.

Abstract:
Beside a demonstrated theoretical formula that describes the variation of diffracted order angle as a function of time, another formula about the scanning velocity of an acousto-optic deflector is successfully demonstrated with experimental results very close to the theoretical formula. This deflector is obtained using laser beam interaction with frequency modulated ultrasonic sinusoidal wave in water. The particular attention that devoted to select the best experiment method of measuring scanning velocity has enabled us to find promising results; the scanning velocity of each diffracted order varies linearly according to modulating signal frequency as well as frequency excursion and sinusoidally as a function of time. Furthermore, the scanning maximum velocity of the pth diffracted order is p times the first diffracted order.

Abstract:
We analyse the competitive effects which alter the stability of SBS phase conjugate mirrors when the laser operates at repetition rates between 10 and 30 Hz. Satisfactory results are obtained with nitrogen gas cell at 180 Atm. We also propose and experimentally demonstrate a SBS phase-conjugate Nd:YAG laser source with a beam steering function. The laser, designed as an oscillator-amplifier configuration, incorporates a TeO 2 acousto-optic deflector on the low energy beam. The high energy beam (100–185 mJ) is thus deflected over 2.7° and 40 resolved beam directions are obtained with 5 µs access time.
