Control of the characteristics of a calcium molybdate collinear acousto-optic filter

The problem of controlling the characteristics of a calcium molybdate collinear acousto-optic filter using acoustic trains of variable duration is investigated experimentally. It is shown that electronic restructuring of not only the central transmission frequency but also the transmission bandwidth of the filter as well as the form of the transmission curve is possible in collinear acousto-optic filters. The frequency characteristics of the filter are measured by synchronous and inertial methods. The experimental relative-transmission curves and the experimentally measured side wings of the transmission bands of the acousto-optic cell are presented. Zh. Tekh. Fiz. 69, 76–81 (December 1999)
