Laser stabilized by acousto-optic cells for optoelectronic oscillators

Résumé

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 10(8), differences between RF signals are up to 2 MHz. We send an extraordinary polarized laser beam on the cells ultrasound at Bragg angles of light incidence. It helps to perform a critical alignment of the two cells.
