Abstract
An acousto-optic (AO) modulator that converts a frequency shift of optical radiation into the amplitude modulation of light at the double acoustic frequency is proposed and described. A ТеО2 singlecrystal modulator mockup that was developed and tested provides the amplitude modulation of linearly polarized optical radiation at a wavelength of 0.63 μm at the double acoustic frequency, which is equal to ~82MHz.
