Several years ago, Shiren, Arnold and Kazaka achieved an acousto-optical analog of optical phase conjugation via degenerate four-wave mixing in glasses. These experiments, which were conducted at 9 GHz, involved the generation of a time-reversed acoustic pulse from a pulsed acoustic probe wave utilizing microwave beams as the pump waves. Here, we examine the reverse situation; i.e., acoustic beams serve as the pump waves and the probe is electromagnetic in nature. It is shown that the medium generates a phase conjugate electromagnetic wave and the physics of this effect is examined.
