Abstract

The acousto-optic figure of merit M₂ of the InI single crystal has been measured using the Dixon method at a laser-radiation wavelength of 1.15 μm. The maximum measured value was M₂ = 1100 × 10^–15 s³/kg. It is comparable with the figures of merit of the most efficient acousto-optic materials: TeO₂ and KRS-5. The velocities of longitudinal ultrasonic waves along the basic directions of the InI single crystal have also been measured.
