Abstract

This paper describes the development, manufacturing and testing of acoustooptic (AO) modulator made of bismuth sodium molybdate NaBi(MoO₄)₂ crystal. Despite the rather long interest in NaBi(MoO₄)₂ crystals as possible AO material, there is no information about their practical use in acousto-optics. The isotropic orthogonal interaction geometry was used, a longitudinal piezoplate was used as a piezoelectric transducer, the acoustic wave was directed along the crystallographic axis Z. The modulator has shown a high diffraction efficiency (up to 87%) with an RF power of 2.5 W. NaBi(MoO₄)₂ is characterized by manufacturability during crystal growing and during mechanical processing and optical homogeneity
