Abstract
The acoustic and acousto-optic (AO) properties of the Ga10Ge15Te75 glass, which is promising for creation of AO devices operating with the near and middle infrared optical radiation, are studied. In this paper, the experimental results for the longitudinal and shear acoustic waves phase velocities and the AO figure of merit (M2) in case of isotropic diffraction by these waves are presented. All measurements are carried out for the 3.39 µm optical wavelength. The obtained M2 magnitudes turned out to be close to 1000·10–15s3/kg that significantly exceeds the typical values observed in germanium (Ge) crystal – the basic material for middle infrared AO devices fabrication. The experimentally determined longitudinal acoustic wave attenuation coefficient for 100 MHz ultrasound frequency turns out to be 1.32 ± 0.05 cm-1. Finally, the acoustic and AO properties of telluride based glasses with the close chemical composition, namely Ga10Ge15Te75, Si25Te75 and Ge25Se15Te60 glasses, are compared.
期刊介绍:
The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid.
In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
