Abstract
Three acousto-optic materials, ТеО2, SiO2, and LiNbO3, widely used in production of acousto-optic cells for pulse modulation of the multicolor optical radiation, have been compared. It is demonstrated that the ТеО2 acousto-optic cell has an undoubted advantage in terms of the electric power consumption, first of all, due to its high acousto-optic figure of merit, while SiO2 and LiNbO3 cells are preferable from the viewpoint of the lowest distortions in transformation of electrical pulses into optical signals. Main theoretical conclusions have been confirmed by experiments on modulation of the multicolor Ar laser radiation.
