“…( The acousto-optic figure of merit (M 2 ) of chalcogenide glasses were determined by the Dixon-Cohen comparison method, 26 and its schematic diagram is shown in Figure 2B. Single-crystal Ge was selected as the reference material with the size of 10 × 10 × 20 mm, and the experiment verifies that the M 2 with the longitudinal ultrasonic wave along the (111) crystal orientation reached the maximum (M 2 = 120 × 10 −18 s 3 /g @ 10.6 μm) which is basically consistent with the experimental standard value reported in the Ref.…”

Acousto-optic interactions based on the diffraction of light by acoustic waves have been widely applied to acousto-optic modulators, acousto-optic deflectors, and acousto-optic Q-switch since the advent of lasers. [1][2][3][4] Materials with high acousto-optic figures of merit have been employed to further improve the performance of various acousto-optic devices. Chalcogenide glasses are considered outstanding infrared acousto-optic media on account of their excellent infrared transparency and high figures of merit M 2 (M 2 = n 6 P 2 12 ∕ V 3 L ,where n denotes the refraction index, P 12 denotes the photoelastic coefficient, ρ is the material density, and V L is the ultrasonic wave velocity). 5,6 Moreover, the optimization of the acousto-optic parameters of glasses can be achieved by adjusting its composition. After annealing, glasses have good optical quality and are prone to process in large areas, which are suitable as media for various acousto-optic devices. For example, Ga-La-S glass was used for acousto-optic deflector at 0.63 μm, 7 As 2 Se 3 glass was used for acousto-optic modulator at 1.06 μm, 8 and Si-Te alloy was used for acousto-optic cell at 3.39 μm 9 etc.

The Q‐switched material and device have attracted extensive attention due to their irreplaceable role in pulsed lasers. In this paper, BaO‐TeO2‐WO3 glass (BTW glass) with sound velocity and sound attenuation coefficient of 3422 m −1s and 0.653 dB/cm is successfully selected and fabricated as acousto‐optic material. Both free‐spaced and fiber‐coupled acousto‐optic modulation devices based on BTW glass are designed and fabricated. The primary parameters such as diffraction efficiency, polarization extinction ratio, and insertion loss are comparable to or even surpassed that of commercial devices. A 1064 nm pulsed laser is successfully realized with a BTW glass free‐spaced acousto‐optic modulator. The maximum optical conversion efficiency, the narrowest pulse width, and the maximum single pulse energy of the 1064 nm pulsed laser are 32%, 54 ns, and 242.6 μJ, respectively. Both the device and laser performance indicate that the BTW glass is a remarkable acousto‐optic material.This article is protected by copyright. All rights reserved

“…Monocrystalline materials take a special place in the field of acousto-optics. Among the most common and frequently used media are crystals of tellurium (Te), lithium niobate (LiNbO 3 ), and TAS (Tl 3 AsSe 3 ), as well as various mercury compounds [ 7 , 8 , 9 , 10 ]. Nowadays though, a paratellurite (TeO 2 ) crystal is used as a working material in acousto-optic devices most of the time.…”

The two-dimensional square-lattice phononic crystal is one of the recently proposed acoustic metamaterials. Strong anisotropic propagation of elastic waves makes the material promising for various potential applications in acoustics and acousto-optics. This paper presents a study of the propagation of elastic waves in two-dimensional phononic crystals based on fused silica. The band structures of a phononic crystal are obtained by solving the wave equation in its variational form by the finite element method. The main phononic crystal acoustic characteristics that are of practical interest in acousto-optics are calculated based on the analysis of the dispersion relations. It is shown that the choice of the phononic crystal geometry makes it possible to control the distributions of both the inverse phase velocities and the energy walk-off angles of acoustic modes. The calculations of the acoustic modes’ polarization are in a particular focus. It is demonstrated that under certain conditions, there are exactly three acoustic modes propagating in a phononic crystal, the averaged polarization vectors of which are mutually orthogonal for any directions of the acoustic wave’s propagation. It is argued that the acoustic properties of phononic crystals meet the requirements of acousto-optics.
