Abstract

A method is proposed for obtaining an amplitude-modulated optical signal of a sinusoidal shape with a given frequency. The method is based on adding two circularly polarized waves with different frequencies generated as a result of acousto-optic interaction in a gyrotropic crystal. Amplitude modulation of the radiation of a He–Ne laser (λ=0.63  μm) at a sound frequency of approximately 36 MHz was experimentally obtained.
