Abstract

We investigate application of acousto-optic cells based on a TeO₂ crystal to stabilize a microwave signal generated by an optoelectronic oscillator (OEO) based on a MgF₂ resonator. Bulk acoustic waves at two radio frequencies (RF) near 60 MHz are launched in the two identical cells providing a required locking on of a microwave signal. When quality factor of the optic resonator is typically of the order 10⁸, difference between RF signals are up to 2 MHz. We send an extraordinary polarized laser beam on ultrasound at very low Bragg angle of light incidence. It helps to perform a critical alignment of the two cells.
