Abstract

The noncollinear acousto-optic filtration of diffracted Bessel light beams in uniaxial paratellurite crystals has been investigated. With the use of the method of overlap integrals it is shown that independently of the order of Bessel light beams in the conditions of transverse phase-matching of diffracted waves within the range of optical spectrum 0.4-1.1 nm in paratellurite crystals the bandwidth of transmission ∼0.52 nm is reached due to detuning from Bragg’s synchronism only.
